Hi.. im faznur.. i have a problem to make my report about Offset Lithography Process Control. this report must submit on 22nd april 2008.. until now i didn't get the information about my report even i search the internet...until i find this group..... i hope anybody can help me as soon as possible... tQ....
My lecturer give a question... the question is.....
1. Why should colour bars be use?
2. How to measure the colour bars? Describe the equipment used to measure the colour
patches.
3. Explain about the various measuring patches color bar?
4. Why is it necessary to ensure that the cmyk ink supplied conform to the required
standards? Explain their implication on the printed result.
5. What is the result of running higher solid densities of c,m,y,k then recommended for a
particular substrate e.g. coated paper.
6. What do you understand about ink trap? Why is it important to control it in printing?
7. Explain the relationship between in film thickness and ink saturation when referring to
solid density.
