Roll Up Roll Up Roll Up - part 3 of 1 2 3 4

This then is the back drop to the tip we are presenting. The method is simple, you roll up the unprinted paper (or the print) in a short length of canvas inkjet media which is on a 3-inch core, making sure that the curl is being reversed. The canvas gently forces the delicate surface around the core, holds it tightly and does not scuff it or crinkle it. If the paper is to be left wrapped for more than a few minutes we slipped an elastic band around it.

How well does it work?

The image shows a sample of flat-stored, sheet, baryta paper standing on a flat surface. It has assumed a complicated curl, up at the edges, generally curled upwards across the short edge but with a hump in the middle. We measured the residual curl with a vernier depth gauge, flattened the sheet with the method described and then measured again. We tested 'wrapped up' time intervals of 1, 4, and 10 minutes. Most of the benefit came after one minute. After the 'uncurling' the sheet remained at the better level of flatness for at least three hours (when we put it away again!). The initial level of curling (a maximum of 10.5mm) was sufficient for these sheets to have suffered from both head strikes and skewing when they were used in a Paper Chase test (in an Epson 3800).
