Don't bother, it's getting pretty ridiculous.

John, regarding inline industrial cameras: if the sensor is working in a controlled environment, its spectral response is known and an ICC profile can be generated for it, doesn't that make it predictable and suitable for color measurement?

Wow, that was very dramatic. I have no idea what you're talking about. Maybe someone else can help me out here?

Sorry, is this a second post in a series? I don't understand what the "new technologies" are, who the "new inventors" are or the "grandiose schemes" etc. Can you please be less cryptic?

Perhaps what you are looking for is images for evaluation, not calibration. An example of good subjective test images is the roman16 bvdm project. Highly recommended.

The ink pump has a conductivity sensor built into it (the electric board is submerged in the ink tank). The sensor might drift or lose its calibration, so you need an external measurement device to recalibrate it.

Erik, in Indigo presses conductivity is measured inside the ink tank. That's the term used by HP, anyway. In your explanation, is the measurement done on the printed sheet?

That ability already exists in every other digital press on the market.

Is the mark the same width as the roll or as the printed image? Try to print two small jobs in a row, but disable the cutter between them (wait for some time before sending the second print). This will tell you whether the cutter is marking your paper, or is it something else related to...

I doubt the version of CS is related to the RIPping problem. If the PDF is exported to a low compatibility level (such as 1.3) there should be no problems RIPping it. When you say "a .pdf that would not rip", what do you mean? What is the exact error message you receive?

I have a personal theory (which I apply to myself therefore it is 100% correct. :p), that says you cannot be both highly creative, and have good technical skills at the same time. In other words, you can't design very creative graphics and also create the job in an accurate and technical minded...

That's really strange. If I see correctly, the black version is composed of CMYK. All the colors split but stay in registration, which probably means it's a global problem and not related to the black ink or the data that it receives. Maybe the print-head encoder is the problem. Some things to...

What is the printing direction (paper movement) in the attached image - up-down? It seems to me as though there is a problem with the data flow to the print head at this area, or maybe with the encoder that's controlling the head. I don't believe this is due to paper distortion - that would...

Thank you both, guys.

Thank you very much, Gordon, for your explanation. Oh, rest assured, I've already read your entire blog, and I use it for reference every now and then. You did an excellent work there! I know, that's why I'm writing the presentation! :) Thanks for the suggestion, but unfortunately the...

Hi everyone, I'm writing an educational presentation on screening, and I'd like to include information on the analog halftoning process. For the life of me, I couldn't find a picture of the glass screen used in olden days. If someone could post a close-up image of the screen (even from a...

I feel for you, Magnus. I miss i1Share too. It's very annoying that X-Rite dropped support for it, and their alternatives are simply useless in a production environment. One good alternative is SpectraShop from Robin Myers. It costs $95, and from its demo it seems like a very good product and...

A digital printshop I worked in several years ago had a graphic designer client come over to approve the print. After many proofs and changes, she asked for one more: "can you add 1% magenta?". The press operator, fed up with her, went to the press and simply clicked "Print" again without...

Have a look at the Xante Illumina GS. It's a laser printer dedicated to printing on envelopes. I've seen samples some time ago, and they were pretty good.

Hi Green Printer, Sorry for being late - I didn't know the answer so I forwarded the question to management. The response I got was: "We will continue to study the issue and decide at a later date." So there you go...
