Utvärdering av ICC-profiler och profil-inställningar för HP Indigo Press 1000

Det nystartade digitaltryckeriet Digaloo planerar att inom en snar framtid införa ICC-hantering i sittarbetsflöde. Med anledning av detta har en studie utförts där antalet erfordrade ICC-profiler undersöktssamt vilka akromatiska inställningar som bäst lämpar sig för tryckeriets HP Indigo Press 1000.Testtryckning utfördes på sex av Digaloos mest använda papperskvaliteter. Genom inläsning av testkartorhar de olika papperskvaliteternas reproducerbara färgrymder åskådliggjorts. Grundat på resultatetfrån denna testtryckning framställdes ICC-profiler för valda papperskvaliteter. Dessa genereradesmed olika inställningar för akromatisk repro och TIC (Total Ink Coverage). Vid en andra testtryckninganvändes dessa ICC-profiler för konvertering av mellanton-, natt- och snöbilder, vilka trycktespå olika papperskvaliteter.Resultatet från den första testtryckningen visar att HP Indigo Press 1000 återger störst förgrymd påpapperskvaliteten Silverblade Silk, tätt följd av Silverblade Art. De minsta färgrymderna reproduceraspå Lessebo Linné Gultonat och Lessebo Linné Naturvit.Vid perceptuell bedömning av de olika bilderna blev resultatet att bäst tryckresultat uppnås medpappersspecifika ICC-profiler. Detta gäller dock endast i två av tre fall. Vid bedömning av bäst lämpadTIC ansågs den idag på Digaloo använda nivån som mycket dålig. Genom att antingen sänka eller höjadenna nivå bedömdes tryckresultatet öka i kvalitet.Slutligen visar studien även att akromatik i form av UCR ger bäst bildåtergivning i mellanton- ochnattbilder på de valda papperskvaliteterna. De olika graderna av GCR i snöbilder anses dock passaolika bra beroende på vilken papperskvalitet som används.

Vitpunktsförskjutningens påverkan på ICC-profiler vid användande av optiska vitmedel

The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point. TheTC3.5CMYK target was prined on an ink jet printer and measured with different filters for the measurementequipment, GretagMacbeth Spectrolino. U- and UV-filters were used during the testings.From the measurement data ICC-profiles were made to make it possible to watch how the profiles compensatefor the blue change of color that appeared in the data. Although a distinct change of color intoblue were discernible in the measured data there is no evident proof that this cause a final print thatis more yellow. Other conclusions and results are to be read at the end of this composition.

ICC-profilers användbarhetvid gråbalansjusteringav arkoffsettryck

I detta examensarbete har gråbalansstyrning och ICC-profilers duglighet undersökts. ICC-profilernahar utvärderats utifrån den tryckkvalitet de genererat tillsammans med olika papper.Gråbalansstyrning har använts som gemensamma likare för samtliga testtryckningar. Detta tillfördeen variabel som var lika för samtliga papper i utredningen. Här med ökade sannolikheten att ICCprofilerskapade från olika papper, skulle ge en likvärdig kvalitet.I arbetet har många mätningar och beräkningar genomförts. De två främsta anledningarna till dettavar dels att utreda i vilken mån det gick att gråbalansjustera trycket och dels att inhämta jämförbaravärden på likheter och divergenser mellan olika kombinationer av ICC-profiler och papper. Mätdatahjälpte även till att ta hänsyn till de felkällor som fanns.Det var möjligt att gråbalansjustera trycket och det fanns likheter mellan en ICC-profil på olika papperoch även mellan fler ICC-profiler på samma papper. Samtliga resultat och slutsatser var beroendeav att neutral gråbalans upprätthölls under tryckningarna. Subjektiva och objektiva jämförelser visadebåda på att en ICC-profil inte kommer att påverkas av variationer mellan olika pappersleveranser,såvida dessa inte är större än skillnaden mellan de olika papperna.Med säkerhet kunde inte förutsägas från vilket papper en ICC-profil skulle skapas för att ge en högkvalitet på flera papper. Mest troligt var att likvärdigt resultat skulle kunna uppnås på G-Print, MultiArt Matt och Multi Art Silk.

ICC-profilers duglighet vid gråbalansjustering av arkoffsettryck

Adjustment to a neutral colour balance when printing was the starting point in this degree project. Onthis base ICC-profiles were evaluated and assessed. The survey was concentrated on the similarity betweenreproductions on different papers with various ICC-profiles. The colour balancing introduced aconsistent variable between four graphic papers. With raised uniformity the probability increased toreceive similarities between the various combinations of ICC-profiles and papers.Numerous of measurements and calculations have been carried out, mainly to confirm whether or notadjustment to a neutral colour balance is possible and repeatable. Further more this gained in comparablevalues corresponding to similarities and divergences between combinations of ICC-profiles andpaper.The research concluded in the fact that it was possible to reach a neutral colour balance. One ICCprofileused together with various papers and also one paper with several ICC-profiles resulted in similaritiesand formed groups of samples. Since equivalent results could be reached on different samples,it implicated that variations within one paper shouldn’t affect the ICC-profiles. This was valid when thevariations were less than the divergence between the papers.Certain predictions on the question of from which paper the ICC-profiles should be generated to createhighest quality in print hasn’t been able to assemble. It’s likely that equivalent results could begenerated on G-Print, Multi Art Matt and Multi Art Silk.

Utvärdering av digitala provtryckssystem

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult. Proof optimised for uncoated paper shows higher quality than the references, which depends onthe surface of the proofing paper. Comparison between reference paper and proofing paper has takenplace as to differences in colour and paper quality.The Digital Proofing Systems are fully automatic, which demand a quite comprised education forcorrect handling. The purchase price and printing costs vary considerably between the ProofingSystems.

Färgstyrning av kontorsutrustning

Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage. The second stage describes calibration and characterization ofmonitors, scanners and printers. Finally the result of created ICC-profiles is set by visual comparisionof a photographs original colours and a scanned and printed photograph.The results of calibration and characterization were varying a lot. Agfa Chromapress 50i was theonly printer which could produce a succesful calibration. Agfa Chromapress 50i and XeroxDocuColor 12 gave the best results when comparing original photographs with printed pictures ifthey were separated with ICC-profiles. ICC-profiles created for Hp DeskJet 970 Cxi achievedundesirable effects. This was the only printer that gave a bad result both with and without ICCprofiles.The reason for this miserable result can depend on the printers unability to fully supportcolor management.

Reproduktionens inverkan på det slutliga tryckresultatet med djuptryck på MF-papper

To get an optimal print result with rotogravure on improved newsprint, MF-paper, knowledge aboutwhat adjustment that should be done through the whole production is needed. This degree project investigatesthe reproduction’s effect on the final print result.A test print is done at Quebecor World Nordic Interprint´s regular print unit. The evaluation of theprint shows how important the use of a unit adjusted ICC-profile is for the print quality. A comparisonbetween the two separation methods GCR and UCR shows that Interprint´s present ICC-profile, usingUCR as separation method, gives less missing dots. When the cylinder that prints the black ink isengraving whit a slower speed than normal the result shows that the colour becomes a little darker, thedetails becomes clear but the difference is very small.

Kvalitetssäkring av Clas Ohlson AB´s grafiska produktionsflöde

The question formulation in the essay brought up whether Clas Ohlson works today with their graphical productionflow and if that way of working leads to a desirable result in press. After a dialogue with Clas Ohlson it emerged thatthey had certain problems with the material that came out of the printing presses. Certain colours were not reproducedaccording to the stated values that had been developed. In March -08 an analysis of the graphical production flowspresent situation were done at Clas Ohlsons in order to find out how they worked with their production of print materials.In the analysis, their way to work with color spaces, displays, ICC-profiles, PDF-exports, pictures and printerswere examined. Occasional interviews were also implemented with responsible personnel about how they worked withdifferent aspects.Deficiencies were found on almost all examined parts in their graphical production flow. Wrong colorspaces andCMYK-profiles was used in big extent, the displays where uncalibrated or incorrectly calibrated, wrong PDF-presetswas used frequently and it also showed that six different suppliers for their printing materials were used. The solutionsthat were relevant for the problems and defects were later on presented as proposals on measures.

Correlates of the Eysenck personality profiler

In this two part study, 811 participants completed the Eysenck Personality Profiler (EPP) and the Honey and Mumford Learning Styles Questionnaire (LSQ) and 263 adults completed the EPP and the Myers-Briggs Type Indicator (MBTI). As predicted there were many significant correlations which add to the concurrent validity of the EPP. When the overlap of the EPP with the MBTI and LSQ is compared with the overlap of the NEO-PI with the MBTI and LSQ (derived from Furnham, 1996a,b) it appears that the EPP has greater similarity with the LSQ, but the NEO-PI has greater similarity with the MBTI.

Mapping Gray's model of personality onto the Eysenck Personality Profiler (EPP)

The aim of this study was to determine how well Gray's model of personality [Gray, J.A. (1982). The neuropsychology of anxiety: an enquiry into the functions of the septo-hippocampal system. Oxfords: Oxford University Press, Gray, J.A. (1987). The psychology of fear and stress. Cambridge: Cambridge University Press], as measured by the Gray Wilson Personality Questionnaire (GWPQ), can provide a full description of personality as measured by the primary scales of the Eysenck Personality Profiler (EPP) and the type scales of the short version or the EPQ-R. Factor analysis of the GWPQ the Anxiety and linpulsivity scales of the EPP and the Learning Styles Questionnaire (LSQ) showed that the GWPQ seemed to measure general activation and inhibition factors, but not the finer features of Gray's theory. When the GWPQ scales were regressed against each scale of the EPP., it was round that they generally provide only a reasonable explanation of the EPP primary scales. It is concluded that the GWPQ measures general propel-ties of Gray's model, that the linpulsivity and Anxiety scales of the EPP also scent related to the GWPQ scales, and that Gray's model of personality provides only a partial explanation of personality in general.

Neste estudo foi analisada uma paciente, realizando um programa de reabilitação cardíaca associado à pressão positiva contínua nas vias aéreas, aferindo-se antes do estudo e após 6 semanas, o teste de caminhada de 6 minutos (TC6M), questionário de qualidade de vida e ecocardiograma. A paciente aumentou a distância no TC6M de 152,5 m para 520,44 m. O questionário Minnesota reduziu de 62 para 18. A fração de ejeção subiu de 33% para 36%. Na paciente estudada a conduta melhorou o desempenho físico e a qualidade de vida.

Iowa's Living Roadway Plant Profiler, August 21, 2003

This publication is a guide to understanding the Iowa Department of Transportation’s roadside management programs. It offers descriptions of various landscape designs or planting styles used within or adjacent to Iowa’s highway rights-of-way, as well as various plant profiles. In addition, this guide will help you learn more about the value of plants and their contribution to our environment and society. This publication is written for persons having little or no formal training in botany, and technical terminology has been kept to the minimum necessary to maintain standards of accuracy and conciseness in the descriptions. Plants are known by common names and botanical names. Most people prefer to use common names because they are easier to spell and say. Both have been used in this publication. Botanical names are taken from Latin, Greek or “Latinized” words of other languages. Each plant species has a unique botanical name, consisting of the genus, followed by the species. Some botanical names contain additional words after the species name to designate cultivars or subspecies. Plant species are grouped into families by flower structure. Family names are Latin, so the associated common family names are included in parenthesis. Sources of information for this publication are not cited within the text to save space, avoid repetition and make it more readable. However, all references used are included in the bibliography at the end of this publication.

Estructura factorial de la versión reducida del 'Eysenck Personality Profiler'

El objetivo de este trabajo es analizar la estructura factorial de la versión reducida del Eysenck Personality Profiler (EPP-SF), un cuestionario recientemente elaborado por Eysenck, Wilson y Jackson (1996) que permite la evaluación de los rasgos primarios más importantes que constituyen cada una de las tres dimensiones básicas de personalidad. Los resultados derivados de la aplicación de la técnica de análisis factorial y escalamiento multidimensional a las puntuaciones del EPP-SF de una muestra española de 946 sujetos replican los datos obtenidos en la muestra inglesa. La estructura factorial de la escala perfila claramente una composición tripartita y evidencia un aceptable grado de homogeneidad entre los rasgos primarios que constituyen cada uno de los tres tipos básicos de personalidad. Si bien, el rasgo primario de impulsividad sigue presentado saturaciones importantes en más de una dimensión. Este resultado es interpretado en los términos aducidos por el propio Eysenck, y otros autores, sobre la naturaleza multifactorial de este atributo de personalidad. Hecho que viene a constatar la necesidad de realizar estudios centrados en el análisis de la supuesta unidimensionalidad de las escalas que constituyen el EPP-SF.
