This is the HP Latex 260 (previously branded as L26500).

This is an absolute and utter misstatement of fact. HP Latex inks should be immediately ready to go directly to the next stage of production (cutting, grommeting, mounting, or laminating) within minutes of coming off of the printer.

I'll be in Orlando Wednesday - Friday.

Both RIPs are solid choices that will do a good job driving the Mimaki machine. One issue to consider is Media Profile availability for each RIP, that is assuming that you are not building your own.

That is mid '90s technology. I've not seen one in at least 12 years. I believe you should be able to configure it as an older Graphtec cutting plotter, such as the FC-2100 series. This is assuming that the software you are using has the driver. I know that Flexi, CASmate, and Inspire did back in...

Wiggle is normal with the HP Latex L2 machines. The carriage has a lot of mass, and the lateral movement is intentional. Bring your Alternative Minimum Power down to 0.2 in the Media Profile. This is to keep the Dryer zone from overheating when printing on this media.

There can be differences in printed output between these file formats. The difference does not necessarily lie in the colors in the file, but in the way that your programs (design and production software) define the colors in the file. Many commonly-used production file formats are able to embed...

This looks like a pretty neat little device. Using an i1 in the field is a bit of a pain in that it needs to be tethered to a PC. This unit will (assuming that it ships later this year) communicate LAB or sRGB color with a smartphone, making it completely portable. It also is a spherical device...

In my estimation, the HP Latex machines are able to produce more uniform and consistent solid colors than most solvent machines. If you are getting grain in the output, I would: 1. Perform a bi-directional calibration (either automated or manual). This is to re-align the heads to get the ink...

On the contrary, Onyx is doing exactly what it should be doing in a color managed workflow - converting colors in the file into the closest possible output color on the printer. While you can certainly disable color management in Preflight / Job Editor, the cases where you want to do this should...

Moving the placement of the rollers is fine. Just don't click 'Get Media Width' after re-loading the laminated print into the Roland.

I will check into the possibility of doing this. The difficulty is that the lighting environment where the observation happens is critical, these inkjet inks are not opaque and are prone to metamerism. The trickiest images will be grayscale or neutral images, and those with reference (spot) colors.

This is the classic color management problem that I have seen for over a decade in literally hundreds of facilities. You are using a printer and RIP from one company (Roland in this case), media from unknown manufacturers (presumably you know this but did not mention it in your post) but i would...

Banding is typically correlated with two major causes: 1. Nozzle Performance - missing or deflected nozzles 2. Feed Adjustments - most plotters (including Roland) include the ability to perform Feed Calibration adjustments to dial-in the feed distance to the media. Only after these (and...

Water-based Latex ink may be more susceptible to the effects of Plasticizers on the print surface than other inks that are more chemically aggressive (solvent for example). As mentioned previously, all PVC banner medias contain plasticizers. They are there to make the media pliable. Don't...

On the Graphtec's front control panel: Menu button > 1 Tool > Down Arrow > 4 Condition Priority > 1 Manual > E Set > Down Arrow > 1 Tool Select > 2 Disable > E Set This causes the plotter to ignore pen settings coming from the software, and always use the values defined in the plotter's...

This is a fairly common issue with PVC banner media. It is called Plasticizer Migration. Plasticizers are in all PVC banner medias to promote flexibility. Over time, and with the aid of heat, the plasticizers move to the print surface, and cause the ink to not adhere or cause roller marks, etc...

The Q-series is a rebranded Graphtec, but it's firmware will typically not allow the use of the Graphtec plug-ins. You'll need to configure and drive it from Flexi's Production Manager. It sounds like perhaps your job file is not set-up properly in Flexi - you need to have path(s) defined as a...

The media is being over saturated with red ink. You need to reduce the amount of ink that is going down to produce the red.

I have to assume that you are referring to the HP Latex 260 (formerly known as L26500). There is no latex machine from HP called L60 nor is there a 220. There are lots of posts on this site that describe users opinions on the machine. Check out the HP Forum and read.
