Some of the example work in ColorLab has a highly desirable edge starve effect. This effect is the result of a printing plate creating an impression in the paper and ink flowing to the outer edges — creating a lighter ink tone in the center.
We haven't found an automatic way to achieve this effect in Procreate. But here's how illustrator Robin Banks created this effect in the preview images:
"After I have my keyline art complete, I double the layer up. On one copy I set a gaussian blur to 1.8% and bring the opacity way down to like 20%. On the other layer I blur it maybe .5%. Then I merge those.
After that, I will rough up the lines with the print defect bushes and erase a little in the middle of the line.
Finally, I use the dry nib brush as an eraser, with the opacity really really low to erase the middles of my lines in random areas and any spots where a couple lines meet."
