Abstract [sv]

This degree theme work aims to evaluate the present ICC-profile and printing ink of Dalarnas Tidningar AB. The company has changed printing ink quality and wants to evaluate how the present ICC-profile work with the new printing ink. 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 comparing material. An densitometer was used to measure the technical parameters of the printing. IT8-charts and RGB-charts was measured with spectrophotometer. La*b*-values, CMYK-values, graybalance curves, color deflections and color gamuts 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 evaluate the function of Dalarnas Tidningar AB´s ICC-profile with the present printing ink quality. The IT8-chart from todays testprinting was oppened in a program for textediting to have access to La*b*- and CMYK values. The values from the earlier 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 darker shadow regions which can make loss of details. An higher saturation is recieved in the red and yellow area while the green 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 printing ink. The dark tone reproduces with decreased luminance, however.
