Document Summary
Grc 101 || week 3 lecture (m) || guest lecturer: professor twomey. Specifies, buys, and directs packaging for the retail products they produce. Company that transforms raw materials into materials used for printing. Entity that fulfils product; actually puts product in package. Mostly used for packaging, also used for publication. Presses (aka in-line press): can be small or big (7. 5-110 inches) Tooling (making of printing plates) have high costs. Companies send designs to printer in the form of a pdf. Dot gain (tonal value increase - tvi) Causes problems if dot gain makes words illegible; images inaccurate. I. e. 50% on dot plate = 78% printed dot. Tone reproduction curve demonstrates difference in sizes. Solution: make dots smaller in file to make printed dot smaller. When minimum dot prints, it gains between 8% and 16% Note: traditional flexo halftone screening makes it impossible to image a dot below a certain size. Colors can be misprinted/do not match original image.
