Pappersmakulatur vid Bobergs Tryckeri AB - orsaker och förbättringsförslag

Pappersmakulatur uppstår i tryckpressarna, men orsakerna finns i företagets alla funktioner. För ett framgångsrikt förbättringsarbete med att minska makulaturen krävs därför att all personal är engagerad.Examensarbetet utfördes på Bobergs Tryckeri AB i Falun, ett familjeägt företag med 60 anställda, som producerar personifierad direktreklam och blanketter. Syftet var att undersöka hur pappersmakulaturen kan minska och målet var att hitta orsaker samt ge förslag på åtgärder för att minska den.Genom intervjuer med personalen kartlades produktionssprocessen och utifrån det utarbetades förbättringsförslag. Exempel på förbättringsförslag är att kontinuerligt mäta och rapportera makulaturen, förbättra kommunikationen mellan avdelningarna och utveckla färgstyrningen. Litteraturstudier och kontakter med nyckelpersoner inom branschorganisationer och andra liknande företag, var till stor hjälp i arbetet. Fördjupningsdelen i projektet har sin grund i boken The Printer’s Guide to Waste Reduction av Tim Dalton.

Gloss and gloss variations inelectrophotographic print = Glans och glansvariationer i elektrofotografiskt tryck

This degree project was performed at M-real Technology Centre in Örnsköldsvik. The perpose was to investigate thedifferences in gloss and gloss variations between chemical and ground toner and different paper grades in electrophotographicprints. Gloss is a property that gives the impression of a higher quality of a product. Therefore it is of great importance toaccomplish high gloss in advertising print.A test chart was printed on three different uncoated paper grades on three different printers. Thereafter, gloss, glossvariation, surface topography, print mottle and density were measured. A visual evalution was also performed. A multivariateanalysis was acheived of the data in order to find correlations between the measured variations.The results showed that paper grades with large surface roughness gave more variations in surface topography and glossvariations (both visual and measured) in print. A rough surface also gave more print mottle. Ground toner gave moresurface topography variations and mottle which increased with the amount of silicone used.

Studie av web to print samt kartläggning av kunders behov för tillämpning av systemet CiPublisher

Customers put their printing suppliers to severe claims for shorter production time and faster deliveries.Printers always look for new solutions to increase the satisfaction of their customers. Oneexample of such a solution is web to print, where the customers book their printed matters atInternet.The solution involves design of printed matter by using templates that are made unique for thecustomer's printed matter. Web to print is suitable for reiterated printed matters. By using templatesthe customer doesn´t have to redo their layout for every new edition. Bromma tryck AB hasinvested the system CiPublisher, which is applied for the customer to make their printed matter atInternet.The purpose of the examination work is to investigate the needs of the customers of Brommatryck for a web to print solution and how such a system should be adapted.The result shows that the customer who is in need of a web to print solution wish such a system tobe easy managed and also usable. The customer inquiry also shows that most of the customers primarydesire for start using such a solution is that it will save time and also simplify the process formanufacturing of printing matters.

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.

Informationssäkerhet inom grafiska företag

The study shows the current need for security solutions concerning work with information in different areas.Investigations will show important solutions for printers��� needs to meet the increasingly harder demands forfast and safe digital communications. Important factors to be analyzed in the investigations are: access todifferent types of information, workers authority of information, access to the data base register internallyand externally, production solutions for an effective fault detection and data base solutions fororders and distribution.Planned and unplanned stops result in a standard of value in interruptions. Internal data bases areprotected by so-called “Fire Walls”, “Watch Dogs” and Virtual Private Networks. Offset plates are locked infor a definitive range of time. Subsequent destruction and remaining sheets are shredded and recycled. Alldocumentation is digital, in business control systems, which guarantees that no important documents arelying around in working places. Fault detection work is facilitated by the ability to fully track the order numberson incoming orders.

The digital printing market is changing faster now than before and the ability to adjust to newsituations has become more importat to a printing company. An efficient internal communicationis essential. At Elanders Digitaltryck a decision was made in august 2002 to look over the shiftworking system for the printer operators. In this paper, an investigation of the possibilities tochange the existing system to a better one was made.The project resultet in four different timetabels. The construction was based on theoretical studiesand an analysis of the current situation at the workplace. The analysis showed that a strong resistanseagainst a change of the working hours exists among the workers and that this should beconsidered before a decision is made. An analasys of the printers counters shows that they areused more efficient during shorter shift periods compared to the longer ones. A closeer look at theabcense due to sickness shows that it is relatively high but no connection between abcense andworking hours could be made.Working hours is a sensitive issue and should be treated with care. It is important that the workersare well informed and preferly involved in the development of a new timetable.
