Here is a link to a series of video tutorials for various RIPs (including Onyx) and design apps (including Adobe) for handling white ink. Your questions are all answered in these video segments: https://www.youtube.com/results?search_query=lee+manevitch+hp

Not sure on the first question. The data buffer in the printer is much larger than on previous generation Latex printers, and the printer is able to accept the entire job as fast as the network allows, without starting and stopping the data flow. Once the job data has been sent to the printer...

PM sent to the OP.

There is a test plot to assess Optimizer printhead performance - see attached. It is located within the Optimize Quality screen. Use 54-inch wide media or larger for this diagnostic plot.

The value of white ink on clear media comes down to the substrate that the media is being mounted to. If the substrate color is white (or nearly so), in many cases that should provide sufficient contrast for the ink to be reasonably visible. Glass substrates are more unpredictable, as they tend...

Yes, date expired printheads can be installed and used with Latex printers.

Also, ensure that your inks (particularly the light cyan) are not significantly expired. Also note that there is about 30ml of each ink color in the ink delivery system, so even after replacing ink, it takes a while for the fresh ink to get to the printhead.

0.2 inches per side is the minimum margin for print-only jobs. When printing and cutting, there needs to be more space for the fiducial marks to be registered on the cutting device. This reduces the width of the job.

0.4 inches less than the media width (0.2in each side).

Agree. Also check and clean the rubber wiper blade on the maintenance cartridge (if present). It can collect ink and lead to short-term cross contamination of inks that are delivered from the same printhead.

Pretty sure that Flexi Basic does not have the ability to create or edit print modes. Higher end versions of Flexi do offer this ability.

Verify that your software RIP has the capability to capture color measurements (densitometric and potentially colorimetric), and that the device you buy is supported by that software, as well as any other color capture/ measurement software that you plan to use.

The X-Rite i-1Pro Series (there are several generations of these) are the most widely-used spectrophotometers in this market. Make sure that your RIP directly supports the device model being used.

The best answer is to calibrate your display, and to create a custom print mode for the media that you are using. The latter is performed in Versaworks along with a 3rd-party ICC profile creation tool. Both require a color measurement instrument (colorimeter/ spectrophotometer). The next best...

There is a setting in the Image Quality Maintenance Menu to enable this or disable this, called Color Variation and text-lines Sharpness Correction- Disable this. It is located within the Image Quality Maintenance Menu. See attached (pic is from a 36x front panel for the format will appear...

Uncured UV inks (including UV Gel) need to be properly disposed of through a qualified disposal service and never end up in a landfill.

Is Paneling enabled on the cutter? If so, disable it at the cutter front panel under Settings.

The RV8 material from General Formulations is not intended for digital printing, it is for offset or screen print. Yes, I have a good amount of experience with Polyester, PET, polyurethane, and other films with HP Latex. Historically, some of these have been fairly challenging due to their...

Also - make sure that the printheads are aligned on the R2000. Grain in solid area fills increases significantly when heads are not properly aligned.

Natural paper medias are hygroscopic, meaning that they absorb moisture from and shed moisture to the environment. This can cause expansion or contraction of the paper, and result in tension changes in a frame. Going with a synthetic paper (polypropylene-based) or similar polyester film...
