I use Dry film photoresist from kolon, its great stuff. I had 4 rolls (4x500 ft) from Kolon Korea. It is the cheapest way. You must try this.
Naste, we are run out of Dry Film Photoresist and the next shipment is still on the way, might we buy some of your Kolon Photoresist? One or two roll perhaps?
We usually use Tokyo Ohka Kogyo product.
How do you bought them, from Korea or is there a local reseler?
