Epson Artisan 835 - What are causing these microscopic line streaks?

O.K. - fine - that's a great step ahead to get away with these strange spikes, the RPM option is history, you won't find that option anymore in newer drivers - like in the L805 photo printer.

You may contact farbenwerk, if they would ship to your country, or you may find a local dealer with similar special black inks.



That's pretty easy - the Epson 4 color printers - specifically those entry level workforce models like my old WF-2010W - use a black pigment ink tuned for matte papers - for a crisp and contrasty print on normal paper. This ink is not used to print black when you select glossy/photo papers , the driver mixes black from the CMY inks. This creates a weaker black level since you have the CMY inks with a lighter luminance mixed in. But if you would fill your black ink in all CMY ink channels you get what you want - printing black via the combined CMY ink channels.

Thanks for the reply. This is great news, never knew such printers works in this manner. Learning something new every day.

You may have a look to the Printfab driver which is a kind of alternate RIP and which lets you set parameters like ink density what most regular drivers don't.

Thank you I will try it, however 1 Gallon is a bit too much

So I've finally bought the prized professional-grade Epson SureColor P600 printer for $250 from a kind lady whose husband was a professional photographer but passed away a few years ago. I found the new ad listing on Facebook Marketplace a few days ago (it was a 4-hour, round-trip car journey). It seems to work fine, but I will calibrate it to clean the nozzles and perform alignment tests, then do PCB print tests.

The P600 came with a box full of professional photography accessories. This caught my attention, and I can only wonder what it is used for. Perhaps checking a printer's color accuracies?
