It's been a while since I last touched base. I've received all the required materials needed for printing transparencies and will continue to update on the progress. I've been extremely busy with university and life's obstacles. I'm not sure if Propylene Glycol works similarly to...

Why is glycerin and glycol used? For ease of ink flow? I know it is also used to dissolve the clear ink from printheads.

Thanks for the reply. So, pigments are larger in their chemical composition compared with dye inks? I think the viscosity might be greater in the pigment if it spreads less, and lower in the dye inks since they splatter too much. Also, it seems the industry is using dye inks for UV-blocking...

To end my curiosity, is your background in pharmacy?

Thanks for the reply. Based on your information, I can confirm that the Artisan 835 uses dye inks. I found the yellow ink to be very translucent, which was interesting to observe based on its chemical composition. Out of curiosity, I did a Google search, and it seems dye inks are about 90%...

Who originally made this formula? I've used 100% RV marine propylene glycol antifreeze with excellent results, then flushed the print head with pure alcohol.

Yes, the Artisan 835 came with a CISS system, not sure if it is using dye. The P600 is using original ink cartridges for the test prints I provided previously. However, I will use refillable cartridges and use UV blocking inks while utilizing only one ink channel. All other channels would be...

Here are the results from a calibrated P600. Extremely impressed by the results. There are some areas that are not as perfect as I'd like; however, I suspect this is an issue related to the medium-quality photo paper used here and how the ink disperses on the surface. I believe that using...

Alright, the cause to the print head issue frying my printer is because the printhead was shorted and wasn't let to completely dry. I confirmed this checking its ohm values of the resistors. The are all high around 15 Million Ohms to infinity. This leads to the possibility that the print head...

Thanks for the reply. I think maybe using ultra premium photo paper and transparencies can also greatly improve precision ink placement. Right now I am using regular photo paper.

If anyone is curious why I am putting so much effort into Epson/Canon printers to make precision PCBs, it is due to the fact that I have always had a negative view of them for about ten years. However, after seeing some prints on this thread, I became more interested and now have a more...

So I've cleaned and setup an Epson 1400 to see how well it prints the high precision PCB traces. It did a terrible job on it. Not sharp and clear. Now I suspect the Epson black ink channel (the physical nozzles and piezoelectric mechanism) degrades more often than other ink channels since it is...

Alright, the printer simply crashed and then died; it does not turn on at all. It seems like the power supply unit or motherboard is fried... I was a bit impatient during the second attempt and did not allow the print head to dry for 4-24 hours. Instead, I air-dried it with a high velocity...

Alright, here is my update on this. My objective is 100% successful in unclogging the black ink channel. I've learned a lot, and much of the information I gained is not available on the internet. I've unclogged every single nozzle, totaling 90 nozzles cleared for the black ink channel...

Hello, I am going to present some information on my attempts to unclog the Epson 1400 printhead using proven methods, such as using solvents like Isopropyl Alcohol (70-91%) and Propylene Glycol (Brand: SPLASH RV & Marine Antifreeze). My first attempt strategy: My first attempt was based on...

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

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

Good news. My theory holds true. The black ink micro-piezoelectric pump channels in the print head are dysfunctional. It is a mechanical/hardware issue within the print head, specifically with the black ink channel, as I suspected. I've imported the original PCB PDF file into Inkscape. I then...

I've done more testing and switched to using Adobe acrobat and makes no difference. So it seems I get those micro-spikes only if I use the option in the Epson driver to enable "Photo RPM (Max DPI)". If I turn off this feature, the micro-spikes disappear; however, the print resolution becomes...

Thank you for the clarification about the behavior of UV light with relation to the D-max value. I will read more about this. I've been extremely busy with school work and it seems like I'll never have time to troubleshoot thoroughly. I heard many suggestions to never supply the photo paper...
