Document Summary
255 result in the brightest colours: cmyk is the opposite of rgb, where 0 is the lightest and 100 is the darkest. Mostly a straight line but has a small bump towards the end (cid:224) doesn"t change the midtones or the shadows (cid:224) the small tip of the highlight dots are changed a bit (cid:224) use a bump curve when you make a flexo plate (cid:224) only affects the highlight of the smallest dot: amount of spread not the same for different sized dots, 50% dot can grow to an 80% dot. Slide 9 dot gain on press when dot gain blows up (cid:224) happens in many different ways if it"s the least or highest point won"t see much dot cut-back. Slide 13: typically have 2 curves (cut-back and bump curves) combined as one curve, a cut-back curve is mainly affecting the midtones.
