Avoid large solids. While lithographic presses have the ability to reproduce solids evenly, toner-based devices have a tendency to mottle, show unevenness, or even banding.
Because toner is fused to the paper surface and not absorbed like ink, it can be more prone to cracking along folds. Thin lines, rules, and headline text across a fold is generally acceptable, but if heavy coverage must be used in the design, be sure to ask your print service provider to score the printed sheet before folding.
Variable text fields, if you’re producing a VDP job, consider the longest word in a field when creating text containers for variable data. Anticipate odd word breaks, especially with variable type in large point sizes by randomly testing some of the data that will be swapped into the design during printing.
Vignettes, also known as blends or gradients, a vignette occurs when one color blends into another or when the tint value changes from lighter to darker or vice versa. Narrow tint ranges force the use of wider bands of tint values, resulting in a visible line between bands. To avoid this, set tint values with a fairly wide range (such as from 15% to 85%) or make the gradient smaller.
Crop marks should be used during the design process to ensure that the whole design comes out during printing. This is recommended for most types of printing, as designs created up to the trim line have a tendency to be cut awkwardly.
