Thanks Tony for your enthusiastic response ;) A lot of good info for everyone, and I agree with what you posted. To be clear, my post was only about data loss when downsampling before even getting to printing. Part of my goal with the Epson p900 is to have a simple set of heuristics to use...

Thank you for your response @Ink stained Fingers To be clear, my post was only about the data loss in downsampling, and nothing that I did in the experiments involved upsampling. So, to preserve the data at 360 ppi, one would only downsample to 720 ppi—no upsampling involved. I am more...

My goal is to establish for me my go-to PPI in Photoshop. So, the experiments were for me, yet I am sharing my results as there may be some interest. As always, I am open to feedback, constructive comments, and corrections to what I have shared below. While building a set of test images to...

Starting with CS6, Adobe no longer included the No Color Management in the Print dialog so for the last 12 versions of Photoshop we have been using a variety of alternatives (and whining about it too :)) That's my 5 cents and I will raise you a quarter ;)

I just noticed that in your instructions you indicated having BPC ON while in all other workflows for Color Target creation it calls for BPC turned off. Just double checking those instructions since it is different (I no longer have the older version of Photoshop yet thought having the clarity...

Great post and thank you. I had heard about issues with Photoshop not fully turning off color management yet have not seen the details. Is there another post or link to an article that explains the issue. Thanks for any help.

I believe you use a Mac so yo have another option using ColorSync Utility build into the Mac software. First you open your file: Then you go to print Now things may be different at some point yet this is what I get. You want to set the print mode to Print Target. I also set the sacle to...

I am not an expert in color measurement or ICC profile creation. I’ve recently revisited this field—working with an i1Pro and ArgyllCMS—as part of some experiments. My day-to-day printing relies on stock ICC profiles, so this is a learning journey. That said, I encountered something during my...

Hi @alexisD I am not 100% sure of what i think the problem is yet several factors fit. Here is my understanding of the issue. You are getting horizontal darker lines at regular intervals in the narrow dimenstion of the A4 paper (perpendicular to the movement of the paper as it comes out of the...

Hi @kawliox I think you should give the light magenta nozzle check another look and compare to the other colors I stitched you two shots into one and you will notice that you should be getting a stairstep pattern with every nozzle and in the Light Magenta, you have straight to almost straight...

Hi @kawliox Are those actually ink stripes or scapes caused by rubbing up against the printer print head? Here is an image of part of the nozzle check for your printer. Each microstep down for each line needs to be straight and clean without significant feathering off that path for all 6...

The experiments I shared below were mainly for tuning my editing/printing workflow on the Epson p900. Yet, I thought others might find the results helpful, so I’m sharing my conclusions and experimental data that led me there. In particular, I focused on grayscale banding differences for...

An inkjet photo printer with refillable ink that can handle 13x19 inch paper is a rare beast, so I may be at the end of what I can suggest. If you back off on the max print size, paper thickness spec, choose cartridges instead of refillable, or allow a higher initial purchase price, you have...

What a hassle. Here is one worth considering, though a bit higher in price. They can be had as renewed/refurbished with a 1-year warranty for $480, yet you can't beat the ink cost. It can handle all the thicknesses of interest, yet it is always best to see what papers are supported, e.g...

I understand the disappointment. The bright side is you did not buy the printer with the wrong expectations or use unsupported thickness paper and cause problems in the printer. I’m sure you will be happy getting back to printing. John Wheeler

You might want to double check that. The only place I found the specs you mention are for the Pixma Pro-10 word for word at this link: https://support.usa.canon.com/kb/s/article/ART153073 Here is a link to a specific alert on what papers not to use in the ip8700 series printers (including the...

Hi Rick It is not an issue of thickness as the ET-8550 supports up to 1.3mm or 51 mil paper. The main difference, I believe, is that the ET-8550 uses a mixture of dye and pigment ink, which will produce different results on the same paper as a complete pigment set of inks. e.g., different...

Sounds like a suitable replacement for your HP K8600. The Canon Pixma iP8720 also has a pigment black and dye-based color ink cartridges. The only thing to check is what card thickness you want supported. What I found online was this: The PIXMA iP8720 can use plain paper that is 17 to 28 lb...
