Prepress Survival Guide (Full Online)

Are  shadows and highlights in your images losing detail? Are your 300-ppi images pixelated on press? Are transparent backgrounds printing solid white? Is there a color cast in your CMYK monochrome images? Are your grayscale photos too dark? Is your line art getting fuzzy at the edges?

The scary thing is, most errors don’t show up until print time. We all find out the hard way that the road from screen to print is not as WYSIWYG as we thought. In fact, the road is lined with snares and pitfalls that can trip even artists experienced in computer layout and image editing.
