GCR = Gray Component Replacement. This controls how and where CMY inks are replaced by K ink in colors approaching and including black.

Graphtec manufactures the Q series for Sign Warehouse. It is essentially the same platform as the FC-series Graphtec. However the Q and FC series machines have different firmware and software drivers that are not interchangeable.

If you are using Versaworks RIP, you can use one of the grays in Roland Color System. Short of building your own color management system, it is probably the easiest way to get predictability in printing grays.

The second and third issues point to problems with the linear encoder/ X-Rail/ encoder strip (goes by different names depending on the manufacturer) or it's sensor. I would look into the procedure for cleaning it, though I can't offer any specific information for doing so on the JV3 250. What...

FlexiSIGN 8.x uses it's own device driver, and does not rely on the Windows driver to communicate with the FC-series printers that support USB. The configuration process is simple: Launch the Production Manager application, define a new device (Setup Menu > Add Setup). Next, select Vinyl...

We profiled the Phototex solvent material on a Roland machine (SP) running Roland's EcoSolMax inkset. It is an easy media to profile if you have the tools to make custom profiles. Bob

No. Once the job has been RIPped and begins to print, all throughput variables have been set, and there is no way to change the speed, aside from cancelling the job and re-sending it using different of print settings. Bob

How do you plan on driving the Graphtec FC5100 plotter? If you are using their plug-in, called Cutting Master 2, then you are out of luck in 64-bit OS environments. On the other hand, if you are looking to drive the cutter from a sign-making application, such as FlexiSIGN, SignLab, or...

The procedure would be as follows: 1. create CMYK vector rectangle(s) of 100% of the colors in question - in this case Cyan and Magenta. Save the file as an EPS file. 2. Bring the EPS file info the RIP software (in this example Versaworks). Double-click on the file to open the Job Settings...

I am still seeing contamination in the Cyan and Magenta. Another thing to try is to print out solid rectangles of Cyan and Magenta with all color correction turned off (density control only in VW). This will only use those colors and save ink in the colors that do not appear to be contaminated...

The nozzle test looks to exhibit cross contamination on all colors except yellow. That would account for the lack of gamut and color accuracy that you are describing. I would suggest: 1) Run a medium cleaning as suggested by Stacy. 2) Run nozzle test print to evaluate. Use a loupe to check...

Inactivity is a problem with any solvent printer. You want to run at least a test print on a daily basis as possible. The first thing to do would be to verify the nozzle performance status by printing and posting a scan of the nozzle test print. The Roland SP-series printers have 180 nozzles...

No they are different. Overprint (located in Job Settings > Printer Controls) will make multiple passes over the same print media, before advancing the media. Double printing is sending the same job two times. On this case, the same print origin must be used (Job Settings > Cut Controls...

What is the error syntax of the message?

Jjstar and Cencalprinter please PM me for the recommendations that you seek. Bob

If FlexiSIGN 7 does not have the drivers for the ValueJet printer line (I don't recall at what point the ValueJets became supported in Flexi), your best bet would be to upgrade the FlexiSIGN to the current version. That would provide the correct driver, as well as media configurations for...

Printing grayscale images well is probably the most demanding type of job for in large-format printing. There are many reasons for this, but suffice to say that it will expose more flaws in your color configurations than any other type of printing. Most RIPs will have a setting that permits...

You can obtain quality output using either data format. The keys are to set your color space settings in a consistent manner in your design application(s) and your RIP software (in this case, Versaworks). Bob

In this case, you are both correct. For the VP series, Roland will void the Second Year warranty in the event that 3rd-party ink is used in the machine. The first year warranty remains in place. Bob

Sorry, by 'data cables' I was referring to ribbon cables in the carriage. Other than fuses, I would say that the next diagnostic steps should be performed by an experienced field service engineer. Bob
