To check for actual printer resolution and optimize it, I made resolution test charts. Also included is the standard USAF -1951 resolution chart. http://www.vinland.com/USAF-1951.html Bertho

Once you degine the feed as transperency,the printer accordingly takes care of.

Thanks everyone.? I've decided to go with the inkjet printer and not risk issues with too-hot laser printing. 73- Nick, WA5BDU

Nick, you've undoubtedly already considered using "Kinko's" to achieve the results you are looking for... ? Not familiar with inkjet transparencies.? I've used high temperature LaserJet

Jetstar makes both types of transparency, IIRC. Leon

When I was working (20 years ago !) I was in the LEXMARK compagny about difference with transparent for laser and inkjet printers there is a BIG difference laser has a HOT ROLL heater around 180° to

FWIW.... I've tried the laser transparencies. The printer didn't lay down enough toner at it's heaviest setting, so I made two of them and carefully overlaid. That worked. 73, Charlie, N0TT On

In the past I have only used Canon or Brother Inkjet Printers. Even with special transparencies for laser printers, I have never got good results while there was no problem with Inkjet Printers. 73

I used to get excellent results with an HP inkjet printer. I don't bother now and get my PCBs made in China. Leon

Hi Nick, I have had much better luck with an inkjet printer and waterproof film used for screen printing than I ever had with a laser printer and transparencies. Very opaque, no pinholes, no need to

I'm trying to get rolling on the photoresist method. I have a Samsung B&W laser printer which I have used for the toner transfer method and hoped to use to print my transparencies for the

What is the nomenclature for the positive resist and where can it be purchased? Thank you. Jim Pruitt

Short wave sensitive.? Unshielded mercury vapor arcs.? Expose through negatives where the trace is transparent, background is opaque.? Develop in the appropriate developer and then put the dye

Negative resist. You use it with a negative. A bottle will last a lifetime. I think it is made by Transene now. https://transene.com/pkp-308pi/ Sam Reaves ARS W3OHM Owner and Moderator of: LeCroy

Is kpr a negative resist? Or positive resist?

A friend of mine uses cosmetic cotton pads(get them at your local dollar store)? to apply Kodak Photoresist (KPR). When it is dry he places the unexposed boards in an old phone book for storage and

I am a little late to the party but have a look at this as it is the easiest PCB software I have ever used. Not free but very
