The Ampad Engineer’s Computation Pad is a specialty pad of paper. Light green with green ruling, the front side of the page has only a margin. The back of the page has a 100 by 700 grid, with each square measuring 1/5″ x 1/5″. The inch lines (every fifth line) are slightly darker.
The idea is that graphs and drawings can be made with the benefit of the ruling, while appearing to be on a blank background.
It is a completely different approach to some of the same problems that Whitelines paper is also attempting to address.
As paper, it’s fairly thin and lightweight. It seemed very pencil friendly, and maybe just a tad less amicable towards a medium nib Lamy pen.
Choices are good. If writing with the intention of line rulings not reproducing was my sole objective, then I’d say the Whitelines paper is much better – using it is pleasant and effortless, while the ruling of the Engineer’s Pad can take some strain to discern. Whitelines also comes in many paper sizes and binding options. On the flip side, the Engineer’s Pad is much easier on the wallet, and each side having a different scheme could be useful.
