Re: exposure unit lighting info

Yea I see it now, I just got this printer last night so it's way different from my old hp
If I have 2 layers on my image, when I print,it should print each layer or I gotta do each layer separate?

Re: exposure unit lighting info

Yes you should. Click the arrow and you may have to scroll up or down. All epson printers have premium photo glossy as an option.

Convert image to CMYK you more than likely have a grayscale. Then change color to 100CMYK print in photo and preium photo glossy paper and you should print plenty dark

Re: exposure unit lighting info

Re: exposure unit lighting info

Florescent lights need to be at 6"or less or it will take forever to expose a screen. The weak light source needs to be close.

Re: exposure unit lighting info

with a exposure box,the closer your image its to the light, the less time it takes to burn on the screen or thats not how it works?

Re: exposure unit lighting info

ok sounds good,ill try that, the halide, i had it at 12" from the screen and it will burn at 23mins,i decide to change the lighting because the heat of the light was making my transperancy useless after it was burn, too much heat.. it was also giving shadows..

Re: exposure unit lighting info

If the halide is not specifically for exposure it doesn't put out enough of the correct spectrum.

The WBP exposes with unfiltered blacklight at 4-5 min. So at 6" with daylight bulbs I would start at 7-9 min.

Re: exposure unit lighting info

I have the WBP emulsion from ryonet, it says 6500k about 30secs or so and 5000k 60secs.. with my 250w halide it takes 23mins...

Re: exposure unit lighting info

This will vary greatly by emulsion type and brand. Day light bulbs take about double the time as unfiltered black lights. So if you emulsion list a starting basis for unfiltered black lights add 35%-50% time to that.
