Re: P800 - Only Black Inks Laying Down

Are you at work now? Do me a favor and right click on the quad you were using and see if it reverted to read only. That happened to me, and the result was very dense black ink negatives as if Print-Tool was printing with no profile. I had to go and right click on every quad and change permissions to read/write in the school lab (which has stricter protocols).

Subject: [QuadToneRIP] P800 - Only Black Inks Laying Down

Hello,

?

Hoping for some insight/suggestions. This is in a school lab setting. Working with Print Tool and a P800 on a Mac Mini M1. IT forced another update, now to Sequioia 15.3.1. This resulted in the QTP800 printer no long showing up as an available printer. I uninstalled the P800 driver and Print Tool, and reinstalled. This was successful in terms of the printer being available. I reinstalled all of the quad files, and I remade the presets. All seemed fine. When printing digi negs, now the printer is only laying down black inks. I checked the quad files and those look as they should with some color inks. I restarted the machine again and all of the apps. No change, only laying down black inks.

?

Any suggestions? (Besides telling IT to stop updating OS in the middle of the term.)

?

Thanks,
DM

When I bought this 7880 for $100, it had been in storage for around a decade. Ink in the lines had evaporated. Still had the original OEM cartridges from 2010 in it. Original owner had run about 250 posters through it, before upgrading to another printer.

?

My investment (in CDN$)

$100 - Printer
$190 - Gloss Optimizer (4x500ml)
$160 - 7880 Refillable Cartridge Set
$150 - Expired ink from eBay
$50 - cleaning solution (1L)

$650 CDN (about 425-460 USD) and I've got this all working and loaded. On to building profile curves.

Many thanks to Paul Roark for his inspiration!!!?

thanks Paul, that's actually remaining availability, I just replaced it. You'll see it's going down,. 24, 23, 22

Your printer may not be able to clean itself because your Maintenance Take is full.

Well, at this point, I've cleaned and checked everything. I'm suspecting that that area in the print head may not be usable. All is not lost. I still have 7 channels and can use this machine to print on Satin/Glossy and stick with my 7800 for matte paper. Or I move the combo gloss/matte to the 7800 and strip down the 7880 for parts.

Good advice Don, I’ll try that next. Thank you for the link.

When I have seen this on Epson 3880, P800, P900, P5300, its usually not the lines nor the damper. Its usually dried crud ink that is floating around the capping station and the bottom of the print head.

This is how I clean these areas -?

?

Have you done this cleaning already? If not, get same paper towels and some cleaning fluid (Pizoflush is what I use, but there are other concoctions you can mix by searching on the internet).

update. I have ink flowing through the magenta line that was giving me problems, but I'm not able to get a proper nozzle check. I also ran a Magenta Flush image file and it was successfully printing but only printed the first half. See attached images.?

Any suggestions? The nozzle check comes and goes and prints in different spots. Also the flush image file printing then no ink coming out... anyone have any ideas for what could ?cause that? Air in the line or maybe the damper is failing?

... working through getting that line to clear on the print head now. Slow going, but getting there.

However, I have all the carts filled as per @Paul Roark's glossy variable setting. Will start printing test patterns on selected papers shortly. Using Richard Boutwell's QTP Pro.

?

*I actually modified a bit. I went with Lc and Lm as separate toners, since I only needed one PK and one MK.

?

Epson 7880 Value

LLK = 50% LM

LM = 10% PK

LC = 15% PK

LK = 50% LC

?

K = 100% PK

C = 50% PK

M = 30% PK

Y = 100% MK

Here is a copy and paste from the v3 instructions from my support site:

?

Step 1: Compare the areas where the transparency material covered is the same density as the coated edges to get your standard exposure time.
Step 2: Find the white patch in that strip to find the blocking density for the time and process you are using.
Step 3: Open the QuadToneProfiler-DN app and go to the Starter Curve Setup screen and change the boost slider so that the maximum black percentage label reaches that blocking density from step 2.

?

The total ink load scales all the inks up and down by the percentage in the slider, and is what is used for using the open bite test utility for direct to plate photogravure. I generally recommend not adjusting this slider for the blocking density when using digital negatives, and only increase it it if the print from first linearization test is much too dark.

?

The Black Ink Boost is what you will use to increase the blocking density for the Black and Yellow channels (which are now combined into a single control and not two separate controls like they were in the v1 and v2 of the QCDN apps)

?

Dear Kim:

Yes, I bought cartridges with autoreset chips and the necessary inks. Carefully prepared the mixtures, filled the cartridges, primed them and use them in the R2880. So far it seems to work. I had 2 spontaneous partial cloggs of the magenta channel. But these could be resolved by head cleanings. I have also refilled the first cartridge. It works. My most activity so far was printing step wedges to learn how to create the quad files. I am based in Austria and ordered the materials from Octoinkjet in the UK. Their Squeezy system for refilling works fine for me.?

Hi !

?

Please find attached an email conversation (as a PDF file) I recently had with Richard Boutwell about the latest version of his software. I think you'll find answers to your questions in this email thread.

?

Overall, I have to say I am disappointed by this software.

?

I paid €100 for this (more expensive for instance than Affinity Photo for instance, but I agree the volumes of sales are not the same...) and :

You feel like the software is not finished (many bugs in the UI, some of them are described in the attached email thread)
The documentation is incomplete (it was at least 3 weeks ago, I haven't checked since then), whole parts are missing.

I feel like I am supposed to take a workshop to understand how to properly use this software and work around the bugs... No matter what the price of the software is, you do not release a fee-based software it if the documentation is incomplete... This is the basic rule #1 of software. Documentation IS part of the software. If you don't have time to document the software, then do not release it. Or hire someone to write the documentation. Or release it, but free & open sourced, with a disclaimer "Sorry I don't have time to maintain or document this software, but feel free to fork it". Of course bugs happen, and are acceptable if fixed someday.

?

I'm really not in the habit of complaining about software, but I must admit I feel a bit obliged to do so.

?

Meanwhile, I've switched back to Peter Mrhar's EDN for gold-toned VDB, which gives me satisfactory results. As a reminder, EDN is free, does not lock you with a specific operating system nor raster graphics editor? and is fully documented in a dedicated book (for sale) or in free videos on YouTube. (By the way, I just found a bad bug in EDN also (about the merge of two corrections), I just emailed Peter Mrhar about it.... :))

?

Your feedbacks are welcome !

And do you use that ink in your Espon R2880? Or in a different printer?

Criss Hartzell,

When I switched to this method my linearization was very quick and when scanning the 51 step step-wedge with my i1 Pro I ended up exactly following the green line in the linearization.

I have emailed Richard twice about this, but so far no reply.? Perhaps he will answer here.

Yes, this confused me too. I made several curves for Pd/Pt and carbon by changing the total ink load to correspond to my blocking density. They worked ok, but, I noticed I was getting star wheel?marks (P900) especially in my negatives for carbon (K45). I decided this was because the ink load was too heavy. When I re-did the curves by making black boost equal the blocking?density, the overall ink on the paper seemed to be considerably less and the star wheel marks disappeared. Also, the linearization was much better. Also, changing the black boost appears to replicate more closely the workflow?in QCDN version 2. I do not have extensive experience with linearization, but that is my recent observation.?

They don't sell the original ink for my Epson R2880 anymore. And I've checked the Epson website for printers that use UltraChrome ink, but they don't sell them anymore in The Netherlands. Does anyone else has this problem to? And what is the solution??
