Ive given up the idea of building my own exposure unit,
and have had no joy in getting a reply from a certain company about their UV units.

But I saw this on Ebay, to me it looks ok, but I just want to see what anyone else think about it,


I cant post the ebay link, but the details of it are;

50cmx60cm (20"x24") Precise Vacuum UV Exposure Unit


This product is equipped with special UV lamps and auxiliary vacuum suction device. After putting the screens and well printed transparency film on the glass, close its cover and let it work after set the needed vacuum and exposure time, then it will make the screens and transparency film close on the glass tightly by evacuating the air of the vacuum chamber emerging from the rubber blanket. When the set time is up, it will deflate automatically, then the exposure is finished. Please cut off the power supply.
It has the same exposure effect with the exposure unit exposed of iodine gallium light. Even if its exposing time is a little longer, but because of its small volume, light weight, low cost and easy transportation, which is much fit for small business and family workshop for making screens with high precision.


The vacuum pumping area (sizes of the rubber blanket) is 19.7”*23.6” (50*60cm), but the optimum screen exposing size is within 15.7”*19.7”*1.6” (40*50*4cm) by the outer sizes.
