First, I am excited to finally bite the bullet and buy my first Piezography system. Many first’s, first time using a Mac, first time using a R2880 (had a 3880 for a short time - wish I kept it)… First time using ABW system, first time using a RIP. Anyway, had many issues starting with the paper just feeding and ruining the paper (solved it by cleaning the grabber - I thought buying a refurbished machine from Epson it would have been clean). Prints came out nice the first day and then the inks one by one started to empty and need refilling (hence the reasoning why I wished I kept my 3880). But I ran into problems. I think this is what happened.
When I had my 4th cart go empty, I decided to refill them all so I wouldn’t have that for a while. I started printing a new job and the contrast was off. It looked like a bad print from a 60’s magazine screen print. I printed a picture that I already had printed the night before and sure enough, they were very different. The new one was much darker.
My thinking was I did one of a few things:
- I put the wrong ink in a cart
- I didn’t shake a couple and possibly got a thicker portion of a lighter color. - could this be the problem?
- I used a wrong syringe in filling a cart.
I thought I was careful in putting the ink in the carts, but it was late and I was tired (after I saw the prints printed differently, I capped the vents and then thought maybe if I simply clean the print heads and forgot that I had closed the vents the night before, I was frustrated and exhausted and went even more crazy before realizing this.) I KNOW I didn’t shake a couple and was wondering if that could be the problem (if the carts unshaken would dramatically effect the cart and if so, did I ruin that ink set?)
How I plan on fixing the issue. One or more of the carts has bad ink so what I plan to do is buy another set of carts and fill them when I am fresh as well as Piezoflush system. Test up to 7 inks until the culprit is found and the printing returns to its intended form. Afterwards, do a thorough maintenance cleaning of the whole printer and start again.
Once I find the culprit bad cart, I have to throw it away as I believe I cannot simply flush it out and filling it properly. I also plan on cleaning all the syringes (maybe I used the wrong syringe). The system is delicate. Writing this post, I am putting GO on my prints and I just ran out of GO, refilled it and went to print and had a bunch of lines (as if it were clogged…I don’t know - I wish I kept that 3880 - 80ML’s!!! ). I did a cleaning and still…lines maybe the air vent is clogged (I initially put the syringe down the vent hole and realized it before I pressed the plunger, but maybe a little came out and the vent is plugged up (again…end of the day tiredness when I went to fill the GO). I just left the vent open and it will evaporate I guess if that is the problem). I do know, I am done printing until I get new carts…find out the bad cart and maintenance the printer and start fresh…and always fill carts when I am fresh!
Anyway, I am excited to be here after the purchase and I am sure there are tricks to the trade that I need to learn. I would love to take the 3 day workshop, but funds are tight and I think I would get more out of it after I learn more instead of a beginner. Can anyone recommend a book or forum threads here on B&W process specifically grayscale calibration so I can have a better workflow from screen to print.
My prints were set to the Gamma 2.2 workspace and I am able to change the brightness of my monitor to 85% (but 85% of what?). How to calibrate it to Gamma 2.2? I didn’t see it in the manual. Do I calibrate it with EYEONE, Hardware (I have an old NEC Multisync 2090uxi color calibrated montitor), or Photoshop? I also want to learn contrast curves that seem to work the best for the Piezography flow. I really want to understand the B&W aspect and have proper tonality in my prints. Anyway, my printing will be down for a few days while I get my new carts and flush so I thought I could work on those areas while I am down.
I want to say the manual was easy to work with in getting the QTR RIP going, the QTR PRINT tool, setting up the printer etc. I have to look to see about the calibration next. But first I have to fix my carts, if my solution is incorrect, then please let me know and advise what I should do.
Thank you in advance
