RE: [Digital BW] Another QTR2 problem... Horizontal banding

2003-08-10 by Daniel Staver

It's really strange. If there was some problem with the printing head or
cartridges I would assume it showed when printing with the Epson driver
as well, but there everything looks perfect. I don't need a loupe to see
the microbanding either, it's clearly visible with the naked eye. The
curves with 100% toner seems to mask out the microbanding, but as soon
as the toner is reduced it shows up again.

Besides that I now get beautiful prints. I've linearized a warm and a
cool curve, and blending between them works perfectly. I printed the
same image where I discovered the posterization earlier, and it now
looks really great. 

I'm also having some fun mixing new toners:

1. Warm curve with K, UT-C, UT-LC and UT-Y inks.
2. Same as above with UT-M toner curve added
3. Mixed my own orange with 30%Y/70%M and used it as a toner in the LM
position
4. 50/50 mix between 1. and 3.
5. 50/50 mix between 2. and 3.

It's very easy to make your own toner. It took me 20 minutes from mixing
the inks to having a finished linearized curve for the toner.
