ICC-profilers funktionalitet vid byte av tryckfärgskvalitet

This degree theme work aims to evaluate the present ICC-profile and printing ink of Dalarnas Tidningar AB. The companyhas changed printing ink quality and wants to evaluate how the present ICC-profile work with the new printingink. Four different ICC-profiles were included in the comparison.One test printing was accomplished with two different separations. Two new ICC-profile was created, as a comparingmaterial. An densitometer was used to measure the technical parameters of the printing. IT8-charts and RGB-chartswas measured with spectrophotometer. La*b*-values, CMYK-values, graybalance curves, color deflections and colorgamuts was compared on screen and on the printed material.Materials from an earlier testprinting and evalution, made by Stora Enso Kvarnsveden AB 2003, was used to evaluatethe function of Dalarnas Tidningar AB´s ICC-profile with the present printing ink quality. The IT8-chart from todaystestprinting was oppened in a program for textediting to have access to La*b*- and CMYK values. The values from theearlier testprinting was supplied from Stora Enso Kvarnsveden AB.The result of this work shows that the ICC-profile from the company, compared with de other profiles, reproduce darkershadow regions which can make loss of details. An higher saturation is recieved in the red and yellow area while thegreen and blue area lose its intensity. The profile gave images which are some contrastless and with a flat reproduction.Today printing ink quality gives more saturation and intensity in the yellow and blue area compared with former printingink. The dark tone reproduces with decreased luminance, however.

Framtagning av ICC-profil för VTAB Backa

The following degree project deals with the production of an ICC-profile, this in the form ofproducing ICC-profiles for VTAB Backa. The company previously had their own profile butthey weren’t satisfied, so earlier this year they started using the TU standard profile, but theyalso wanted a complement to this in form of a profile created for solely their printing press.The separation settings used when creating the new profiles were based on information fromTU and their profile. Two basic profiles were created and then edited to obtain a better result.The test printings made with the edited profiles showed that the less adjustments that are made,the better. It was also discovered that the TU standard profile eliminates the highlight toneswhiles the new profiles are somewhat darker. VTAB Backa has at the end of this degree projectdesided to conduct more test printings before making their decision.

Granskning av kvalitetssäkringsarbetet vid en ICC-profilbaserad trycksaksproduktion

To make your company change from a conventional workflow to an ICC-based workflow you need tomake investments in time and money. On the other hand you get your reward in terms of a stable andquality safe production. To choose this way of adjusting your company to new routines requires accuracyas well as a great deal of commitment. It is not only about having the right equipment. There area lot of factors that affect the quality of production.Our ambition with this report is to bring out the importance of general thinking when it comes toICC-profiling and to discuss on which basis printing profiles should be created. Quality parameters asfor example roughness and whiteness of paper are also discussed. To be able to investigate these mattersin detail we have taken a closer look at two companies, which have chosen to commit themselvesto achive better quality through color management but still feel that they have some problems withtheir workflow.One of the conclusions that are made in this report is that both companies should extend their investmentsin education of employees to become less independent of consultants, but also to increase theinterest in changes within the company. It is also stressed that an ICC-profile only can be efficient if acompany commits itself to accuracy regarding routines, control and calibration.

Microcrédito, emprego e renda: uma pesquisa empírica na ICC-BLUSOL/SC

Esta pesquisa objetivou analisar o impacto do microcrédito junto aos microempreendedores beneficiados pela Instituição de Microcrédito ICC-Blusol de Blumenau, Santa Catarina. De um total de 5.451 clientes foram selecionados e analisados 94, os quais obtiveram microcrédito durante os 10 últimos anos. Para testar a veracidade da afirmação, utilizou-se modelo econométrico utilizando a técnica de dados em painel, através da estimação das variáveis no modelo de efeitos fixos e efeitos aleatórios. Como variável independente utilizou-se a premissa "Valor do Empréstimo" e como variáveis dependentes "Vendas", "Resultado Operacional", "Garantia Real", "Garantia Aval", "Recursos Humanos", "Custos Fixos" e "Custos Variáveis". Conclui -se que somente as variáveis "Vendas" e "Resultado Operacional" validam a afirmação de que o acesso ao microcrédito resulta em incremento de Faturamento e Renda. A criação e manutenção de empregos, embora não tenha sido comprovada na análise estatística, ficou evidente, pois a simples sobrevivência da empresa já pressupõe isto.
