Color optimization

The RIP has an advanced setting for "Color Optimization". I must use the "Clean Colors" option to get pure CMYK output. Thankfully this allowed me to print test patterns of every color, and even every color over white. I then turned this option off to get a black test panel using all colors.

Printing Solid CMYK

I have completed the head adjustments, and everything is printing well. I had been asked to print a large block of each ink color for testing purposes. Our customers have strict performance testing criteria, and we need to see how this off the shelf product does. When I attempted to print a solid block of Magenta, I saw some Cyan in it. When I printed Yellow, I saw both Cyan and Magenta in it. It appears the RIP is attempting color correction. I have started testing every option to eliminate this.

Back from training

I am back from training in New Hampshire, and immediately have an issue. The print heads all seem to be slightly misaligned. Looks like I will be spending the next two days re adjusting everything.

Training in New Hampshire

I am in training in New Hampshire all week. I am learning the image expert / jet expert software and hardware. It will better allow me to quantify the print quality, and can be used to directly access individual print heads as well.

White print head

The white print head is a pain. I had to purge it if it was idle for more than 20 minutes and the nozzles seem to never all want to fire at the same time. After spending all day tweaking, I am finally happy with the output. I am taking tomorrow off to spend some time with the family,so There will not be a post.

Print Head Adjustments

I spent the entire day adjusting print heads, and I still did not get to the white head. I am happy with all others, but the white will be difficult do to trying to see the test patterns on aluminum.

Project Update Review

Working only half a day sucks, but it is even worse when the entire day is taken up by meetings. Today was the project update review. It was great to present the progress made with my project, and even better to learn about the other ongoing projects, but I accomplished absolutely nothing today.
