Today is Sunday, and after personal some reflection plus its hot as heck here, I took another look at the decals. There was something nagging at the back of my mind; The TR-595E’s original front sensor array decals did not have the two white oval-like details for the pair of alternating green LEDs in the middle, just right above the green scanning sensors. I added them in using Inkscape, and I hope the position is correct.
Unlike the MkVII, these pair of details are flat and if you looked closely, they are literally part of the sticker.

Anyway, I think I better stop modifying the decals in case the ‘artist interpretation’ went off tangent. I have not tested the types of media needed for printing but they will be paper, vinyl and clear PVC.
THE PAPER OF CHOICE
For the original decal, and the modified section, I am thinking of using those new 128gsm synthetic PVC paper with matt surface. It claims to be waterproof and also, not easy to tear. I would also like to explore the Avery paper again. A kind shop printed a sample for me on their large format inkjet. Although the ‘paper’ is naturally a light-blocker, its details cannot be acceptable at reading distance. But I have just seen some which comes in A4 and are LaserJet friendly.
THE VINYL STICKER
The only reason I needed some of the designs to be printed on a vinyl sticker is to help cut out the three holes in the Lower Interface piece. The rest is actually for clear Mylar cut-out to diffuse the LED lights.
