I was making them back when we met. I made a few for clients before the world got overwhelmed with digital negs, prints , computer updates snd the rest. Once I finish remodeling this house, I’ll

Hi Eric! Long time no see! Will add your name to the list. I’ve got 10 students and 1 alumnus in the class; we’ll see who continues on in the process after class is done so I can add more names to

I have made many but I’m not currently making them. Sent from my iPhone. So I may not recall what, when, why.... Confirm again later

I found this sensor. Www.nixsensor.com. I was hoping it could be used to read greyscales for platinum printing. -Felix

Thank you Chris - most useful. We shall be most interested to see any amendments too, enabling sharing of views and perhaps tech tips. Robert Sent from my iPhone; please excuse brevity.

Hi All, Compiling a list of chrysotype practitioners. This is what I have come up with from books and searching the web. Anyone not on this list that you all know of? Bob Schramm is no longer alive

Should be 385-400nm! All the Best, Terry Glass

Would these units work for UV exposure? They are rated 390-400nm All the Best, Terry Glass

I went with blacklight LEDs in my revamped exposure unit. They’re in the 380-390 range. I went a little overkill but I wanted to ensure even coverage for the largest possible prints I could make- I

Thanks to those who replied and those who are going to. The photopolymer not responding to BLB may be the reason I am having issues with my PCB etching masks exposure unit. It has a small fluorescent

My experience... Processes that use the photo reduction of iron(III) to iron(II) are broadly sensitive to light at around 390 nm. Thus they work just fine with inexpensive BLB bulbs/LEDs. These

I alternate 360 nm with 420 super actinic bulbs peaking bulbs … . So I may not recall what, when, why.... Confirm again later

If you build your exposure unit with led strips, a good idea is to use alternate strips of 360nm and 400nm leds. This arrangement will probably work for every known process. 360nm leds are much more

365nm to 395nm 365 is optimal for exposure time but more expensive cost wise.

I used to have a nice list of what range of light worked with what process. I suspect it is on the drive that died. I am looking to make a new one because I've seen youtubers use everything from

I will certainly try that instead of the spray glued white paper. I figured out that the incomplete printing of the image was likely a spooling problem. I shut my system down and restarted. It printed

My P800 uses the 17” film To ensure the front edge is sensed every time I run a black marker pen along the front edge -1/8” line Works well for me Edward Working on the go on a screen keyboard -

I am using Mirage. I will try that. Thank you. Thanks, Carlos Carlos Alejandro Photography w 302.234.1100 m 302.547.7799 www.caphoto.com

Maybe you have a roll width of 17" but your printer is not able to print that width? Greetings Cedric Muscat

Hi Carlos, Are you printing with PRINTOOL? If so, try setting the print size to 16.8 inches instead of 17 inches. I had the same thing happen on my P800 Let me know Roberto https://rjprintlab.com
