Re: The HUD market grows

I wonder what type of Photopolymers they want.

Good finding, thanks, I hope work well in small areas.
Maybe a good technique to include in a photopolymer manual.

Kodak used 4 x 5 in plates at 1mm THK.
Agfa used more, 2mm, perhaps

Re: Silver halide sensitivityy enhancer

Formate ions are inserted onto AgBr crystals on formation.The formate absorbs the hole (+) formed after photon exposure. This electron - hole pair is formed after the sensitizing dye absorbs the photon energy and transfers it to the crystal. After "absorbing" the hole the formate forms a r...

Do you have to sign up to this site to read the article?

For me would be interesting to use with pulsed laser masters but I will try to convince my Lab.

Grayham, I can send you my copy, please PM me.

Re: Zilux Photopolymer ...

Congratulations!
Very good result. The exposure is slow however, this is a thing to research. The most difficult thing is to achieve a high efficient master, maybe a DCG, SHSG or even on a pixelated digital image, the last one is the ideal for contact copy, but is very, very rare.
