RE: Tricolor gum, order of layers
Hi Loris Could you describe the paper you use for negatives a little more? You say it is quite translucent, Is it like draughting film (paper) or velum ? Who is the manufacturer? Pictorico here in the UK is expensive too.

With my printer that means: back + light gray + some (very little I presume) color ink... Probably oiling would mask some of the paper texture... I noticed that the paper you mention is a special photo paper. If I'm not mistaking, the printers lay much more ink and use a much denser dithering algorithm with those "photo" papers. Instead, I use a special type of plain paper (which is quite translucent - and less textured / but there's still some texture - compared to ordinary plain paper) and I print using the plain paper profile provided in the printer driver (which lays much less ink and uses a more visible / relaxed dithering pattern), and I think that's the main difference leading to my pointillistic result which you haven't observed. Hope this helps, Loris. 1 Ekim 2008, Çarşamba, 12:13 am tarihinde, Katharine Thayer yazmış: > Hi Loris, > Aaah, I get it now.
