I recently examined a printing project that was a simple brochure with a fade to nothing vignette of black. When it was printed offset, the fade stopped abruptly at 4%, leaving a sharp edge between black and white. Unacceptable to the customer/designer. The file contained dots from 10% to 1%, but offset was losing them. Every plate has a minimum printing dot, so just shoot the designer, right?
Gave the same file to an iGen3, and while it was a little better, the lower tones were lost again.
Finally, the question: What digital printing machine would have enough resolution to do this, or is it something that should not have been designed?
An Epson did a little better job, and the discontinued Iris did the best, with uncoated paper and the ensuing wicking helping out.
Are we at the envelope? (no, it was a brochure...)
