    Star Chart Resolution Tests of the Epson P900

    Thank you for the feedback @Ink stained Fingers. Much appreciated. The P700 has the same print head and printer driver settings. On Mac systems, one needs to use the official Epson driver, not the subsetted one from Apple. The Epson Print Driver for the P900 on the Mac does not give you a...

    Star Chart Resolution Tests of the Epson P900

    Note: I just added the PPI vs. Circle diameter table that somehow did not transfer over with the initial post I ran resolution tests for both PPI image settings and printer Print Quality Settings to determine my go-to settings for good images from my perspective. The test results might benefit...

    Epson L15180: maximum paper weights

    Hi @Laith That is not a good assumption. Right in the table of contents under printing it mentions printing documents or photos for Windows and Mac computers on pages 119 and 143 respectively. Later in the manual they mention many photo papers to use. It’s all in the manual. I don’t think...

    Epson 9880 nozzle issue

    Hi @blur Those symptoms sure line up with the dampers for those ink channels going bad. Check this link out. https://community.inkjetmall.com/t/7880-damper-replacement/6087 John Wheeler

    Epson L15180: maximum paper weights

    Hi @Laith Not too tricky. Here is the reference file from Epson for that printer. They have detailed specs of what papers of what thickness can be used in each of the four possible input points: ADF, Cassette 1, Cassette 2, and rear feed. They also talk a bit about the max paper count it will...

    Recommendations for Reliable Photo Scanning Services?

    I know there are always tradeoffs between using a service and doing it yourself, both in terms of cost and one's time. When it made sense for me to use a service, I used Larsen Digital in Utah. I have used them several times, and they were for family pictures that we wanted to digitize to...

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

    Thanks for the response @Ink stained Fingers I have recently finished about 24 different Siemens Star Chart tests under various conditions for the Epson p900 and captured the results with my copystand, camera, and macro lens. I will post the results after figuring out the best way to organize...

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

    I, too, find many articles outside my photographic interest (and sometimes outside my understanding). I also have to remind myself that what makes a good picture is multifaceted and, for me, what makes a viewer feel something. It goes beyond resolution, color gamut, color accuracy, paper type...

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

    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...

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

    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...

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

    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...

    ArgyllCMS and X-Rite i1Pro2 target sets

    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 ;)

    ArgyllCMS and X-Rite i1Pro2 target sets

    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...

    ArgyllCMS and X-Rite i1Pro2 target sets

    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.

    ArgyllCMS and X-Rite i1Pro2 target sets

    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...

    Observations of Spatial Measurement Variation on the Epson P900 – Potential Implications for Color Target Design

    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...

    Canon TS5150 - Dark Stripes When Printing Images

    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...

    small lines/streaks when printing photos

    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...

    small lines/streaks when printing photos

    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...
