    Star Chart Resolution Tests of the Epson P900

    Epson is varying the resolution nomenclature by printer model, drivers for printers like the L805/1800 or the ET-8550 which are as well photo printers with 1.5pl, available quality settings are 'Standard, High' for the L805 or for the ET-8550 'standard high best' for an Ultra Glossy Photo paper...

    Star Chart Resolution Tests of the Epson P900

    That's a great evaluation - very scientifically - of the practical resolution limits of the P900 printer, I would assume that similar printer models like the P700 and other printers with 1.5pl droplets would rate about the same. One variable would be the ink spread which varies with the coating...

    Am I defecting to Canon ?

    I'm just reading that Canon has presented a successor to the TC-20 printer - it's the Prograph TC-21 , it looks the same as the TC-20, the technical data are almost the same - I see differences here - the printer now comes with an adjustable display/user panel - the printer offer almost...

    Downsample to Twice the PPI of the Detail You Want to Preserve

    Epson is producing millions of their printheads and sell them as well to other companies; the overall design - piezo elements etc was already quite old - it could be scaled to differents widths and nozzle rows, but just look to the printhead of the WF2010W - just an entry level little printer...

    Downsample to Twice the PPI of the Detail You Want to Preserve

    Yes, newer Epson printers - Workforce - Ecotank and large format printers come with 600 dpi printheads - same as Canon's printheads, but the number of nozzle rows on Canon printheads is much higher than on Epson printheads. Canon printheads need a separate row of nozzles for every droplet size...

    Downsample to Twice the PPI of the Detail You Want to Preserve

    That's a great posting explaining the details and effects of up/downsampling; the issue of upsampling to twice the printing resolution is lurking in the background since quite a while like here in Qimage with the 'Overdrive' option. https://www.ddisoftware.com/qimage-u/tech-prt.htm...

    Epson EcoTank L18050 Print head clog

    There are sevearl acctions and options to go after such clog - placing a piece of kitchen paper under the printhead in the printpath and soaking it with a cleaner is one of it. Pull the power cord shortly after you turned on the printer and the head starts moving. The next step would be an...

    Am I defecting to Canon ?

    Which inks for which printer are you looking for ? We have discussed so many variations already. If I look to the TC-20 the Chinese substitutes for the PFI-050 Canon pigment inks could be an option...

    Am I defecting to Canon ?

    I understand that it is difficult for you to make the right printer selection: both the TC-20 and the T3100X are oriented to CAD/poster printing jobs - the word 'photo printing' is nowhere mentioned in the user documentation - not at all - thjis is intentionally but let's not talk about...

    Am I defecting to Canon ?

    6000 prints is already quite a good total, but it's quite similar to buying a used car - is there more information available about previous repairs, what is the warranty status, is the printer covered by an additional warranty expansion , what type of inks were used - OEM or ???. The printer has...

    Am I defecting to Canon ?

    Both the T2100/3100X and the TC-20 are entry level 24" printers as described in detail. one of the limitations (intended by Canon or Epson) are the max roll diameter and as well the paper thickness in the range of 0.27mm - 0.3 mm. Canvas material is typically even thicker than regular paper of...

    ET-7750 Ink pool at hub causing ink smearing?

    i must admit that I'm not really clear what you have done or are trying to do. The main problem with the ET-7750 was the build-up of ink smear from the pigment black ink at the rubber lip which is wiping off the nozzle plate from the bottom. The ink residue is buidling up there, the ink smear...

    Epson P900 and the Role of 16 vs. 8-bit Mode in Mitigating Banding

    Wow - that's a great job you did to work out the intricate details of the 8 bit vs. 16 bit details in image processing and printing. I must admit that most of the images I'm printing are 8 bit jpg images , and some show banding indeed but it's from compression artifacts.

    Canon QY6-0076 eBay Order

    Canon printheads are a consumable item and fail after some time of usage, please read the attached description which explains the internal wear; it might very well be that several generations of printheads over time have improved the situation but it's the ink volume at the end which counts and...

    Colorimeter/Spectrometer Calibration Profiling Advice

    I thought everything is getting esier - simpler now with AI ..........am I missing something ? Issues and limitations of softproofing print output on a monitor was subject of several forum threads already over time.

    Colorimeter/Spectrometer Calibration Profiling Advice

    There are some restrictions to tlhis aproach - printer and monitor are independent output devices and don't know of each other how they reproduce colors. Keep in mind that the gamuts of monitor and printer are not identical, they only overlap partially, and viewing conditions are typically...
