Yes, at this point, my recommendation is that you start a new media preset (media profile) from a new baseline starting point (New SA Vinyl) with no existing linearization data (color calibration = N/A). If you want to use the same ink load and pass count as the existing preset, that is fine...

OK, based on the results of that testing using my file, I think that we can draw some conclusions: 1. With color correction off, the lower row of near neutral midtone colours has a bit of a color cast toward cool (blue). The reality is that the CMYK build value in the file is C50 M40 Y40 K0...

Neutrals and near-neutrals are the colours that are most likely to experience color shifts, as opposed to more saturated tones. The fact that the color shift occurred progressively through one long print run would tend to point to an issue with the printer, and the printheads themselves are the...

The Graphtec serial cable is not a straight through cable. It has pins 2 and 3 crossed, as I recall.

The place to start with horizontal banding is with an assessment of nozzle performance - this is true of all inkjet printers, regardless of ink chemistry. Print and assess the printer's nozzle test print. From that printed pattern, you will likely see evidence of the root cause of the problem...

In the plotter/ large-format printer world, industry norms across most every brand are as follows: Take the list price of the printer, and divide it by 10. That is the price of the annual warranty extension +/- 10 percent. This rule of thumb has been the case for decades, and works on Roland...

This particular Samba fabric is supposed to be compatible with solvent inks, but eco-solvent ink is generally a poor option for most polyester fabrics, particularly those without heavy coatings. I know of businesses who print Samba on Vutek UV machines with success, so a UV printer may be...

The SAi RIP (the one in FlexiSIGN etc) is a functional RIP, but in my experience, it may benefit from configurations to get things dialed-in more than some of the competitive RIP products. You might want to look into getting a free trial evaluation of Onyx or Caldera to compare the output from...

As has been mentioned in this thread, the good news is that there is absolutely nothing wrong with your printer that can cause the problems that you are describing. Mutoh printers are halftone devices, and they are entirely controlled by the brains (RIP) when outputting job files. These issues...

On the L25 it is mounted to the hinged window of the printer. It looks like a silver colored pen. Clean the tip of it (points down at the media when the window is closed. Clean using a lint-free cloth or towel).

This error references a time-out on the Drying System Warm-Up. 'Drying System unable to warm up in the pre-defined amount of time (55c while printing).' Check that the input voltage is in the range of 198-205v Make sure that the ambient room temperature is at least 20c (68f) Clean the...

Are you running Roland's OEM ink or a 3rd-party (non Roland) ink? In some cases, when the printer detects non-OEM ink, more frequent cleaning cycles are performed.

If you define a Graphtec cutter in the Preflight / Job Editor for the job, it will print registration marks and a bar code. Other brands of cutters may well do the same.

Best advice I can give is to print using a higher pass count than you have been using to this point. The Epson DX4 and 5 heads are prone to this type of 'white banding' which appears similar to random drop-outs for several passes. When it occurs, it is almost always visible in in solid colors...

Based on this, your potential savings on ink (30% lower cost) works out to < .05 cents (USD) per square foot. Is that significant, given the potential issues associated with any ink swap (potential need for new profiles, drying problems, color shifts, ink train/ printhead replacements)? Doesn't...

The 86:01 error references a Servo Motor Shutdown event for the scan axis motor. This is the motor that drives the carriage. Shut down the printer when error occurs. The most common way to experience this error is to have a serious head strike with the media (or something else), where the...

The short answer is that different workflows, including files, RIPs, printers and media product, CMMs, and rendering intents, etc all play a role. The effective term is that CMYK and RGB are both process color models, and they always exhibit device dependent behaviors when rendered to a screen...

In a drag knife system (like Roland's), you need the cut point to trail the center of the blade so the blade self-orients. There are a couple systems that employ active blade rotation but the majority of systems are drag knife systems. If your blade offset is too small (worst case 0) your...

Based on the testing that you have done (print with color management on and another with it off), tells us that something in the Media Profile is the culprit. With the SAi RIP, it is relatively easy to get the various media settings misaligned (ink restrictions/ linearization/ ICC) and when that...

Are the bubbles visible in the print zone (area where the ink is being applied), or do they appear after passing through the curing unit? Depending on the answer, I would suspect one of the following: a) Excessive heat in the curing zone b) Relatively old media which has experienced degraded...
