A little vent. Sometimes digital designs do not translate well to a printed paper medium for review and markup. There. I said it. Even the most expensive business printers (not truly meant for graphical output) can sometimes have difficulty in producing effects seen with illuminated pixels. Sometimes gradients that are meant to be subtle print as black blocks of occluding color. Subtleties can be lost.
In these cases use a screened device to present the work and use printouts as lower-fidelity reminders and/or backups.
Thank me later.
