Anyone using Toyo Inks - UK preferably - no offense ;)

Any opinions - good, bad, indifferent?
 
only ever used toyo inks with the waterless toyo plates about 10 years ago
Worked out poor So went back to conventional litho One thing I would say is It was great for solids
 
    • We've been using a Toyo process set for probably over a year now, and I've got mixed feelings about it. It is a strongly pigmented set which can have advantages and disadvantages. The black is so tacky that its been known to pull things apart during printing. The magenta is so strong ... well, we've seen odd staining of the coppers, but that may be chemistry in conjunction with the ink, so whose to blame? That being said, it's a generally really good set, running well at high speeds, holding densities. It can be a little dry on the rollers on light coverage forms causing you to chase the dry-up with water. But even then seems stable on density. But then... its been a good day...
     
    my company use TOYO ink 100% ,process and PMS. since only this brand available in my country plus it cheap compare to other the only one DIC brand. i can not spot any different if it good for solid or spot color but one thing for sure our LS540 rollers are never free and clean from calcium's deposit especially cyan and yellow after long run 24 hour we must do roller cleaner.lucky it all done in auto mode than other our old MAN ROLAND press because usually the will take out all the roller out,line it down and clean it manually.

    over damp,worse quality incoming water supply from tap. things like conductivity,pH, hard water@soft (if i talk it out everyone will sure say"what the hell you are talking about !!!) make the ink really give headache like scumming

    anyway dont blame them(TOYO) my company make a lot of money thanks to them. TOYO forever !!!!!! you make my day....

    Have you tried a hot water and vinegar (or weak acetic acid solution, say 5%) wash down at the end of each week? That should keep your calcium down.

    It is usually the water supply having a high mineral content, have you had this tested? An reverse osmosis unit could help out if you're really suffering from calcium deposits.

    I tell you what it will be interesting to compare how our press reacts with this ink. We've never had any calcium build up in 18 years and 6 presses.

    Some inks do carry calcium as a constituent: so this will prove or disprove the theory that the ink is to blame in your case.
     
    Gday Richard
    I used toyo hy-unity for about 3 years found them to be ok but the mag did seem to leave alot of calcium deposits, had to de-calcify pretty often to keep under control.

    I did a test with TOYO 24/7 brand.. I also had mixed feelings about it. The good, the drying time is really fast = cut down sooner. Also, it seem like the inks matched our proofs better. The bad, you cant leave it on the rollers for very long = if you go home early and the 2nd shift isnt coming in for awhile then you have to wash up. For myself, this was a big issue. I normally use Wikoff that stays really wet, so I could actually leave the ink on the rollers overnight and not have to wash up. Saves me ( and the company ) about 20 minutes a day.. yes i know this isnt the best thing to do for the rollers and I only do it if im running late. So for us, the small increase in price per can using the TOYO plus an additional 20 minutes a day of my hourly wage just wasnt worth it. Also, if your saving plates, you pretty much have to clean them right after they get off the press. I normally just wait to the end of the day to clean my plates, but the ink dries to fast with the toyo.
     
    Ok guys thanks for the feedback - it's good to know what to expect from a new (to us) product.

    Trialling on Monday so I'll post our experience here. Happy weekend ;)
     
    i think only i knew what was the cause of "calcium's deposit" in my company thanks to this forum !!!! you know richard it kind a little weird when 1 day i suggest to my press'operator that i work with to use water as for last wash because i can clearly see all the copper roller are dirty with things like chalk that from what i know is the calcium'deposit. yup he surely use water but just wipe it up using wet sponge instead from run "reverse" an apply water to totally removed all the deposit. he say back with weird expression on his face" why should using water because "water"(he think because the damp water enter into roller train that cause this problem) is the problem", hmmm because a thing call "respect" i have say no more, no arguing . could you imagine if i suggest to use vinegar mix with warm water?

    But water on its own won't dissolve the calcium - you need the acidic action of the vinegar to do this.

    Why not try bringing in a little in a bottle? Then when press is washed up and showing signs of the deposit - stop the press, use a safety stop button, open the roller guards and try it for yourself with a cloth.

    The sequence for wash up would be solvent/water/warm water vinegar wash/dry off.
     
    oppss forget to tell you we use a solution in blue color that make all build up calcium seem like emerged on the roller especially on copper roller surface...this liquid work like make the surface of the roller really dry so the calcium's deposit can be clearly seen so i think just using water only could remove that build up. anyway thanks for the idea of the wash up sequence.
     
    Hi Richard, TOYO a bit notorious for heavy calcium deposits over time. Runability ok. A few issues with duct stability but nothing too tragic. Inexpensive in the short term, Can turn expensive if house keeping poor.

    Hi PC thanks for the info - and welcome to the forum. Just looking through the TOYO data sheets doesn't mention any calcium based compounds.

    Could be the higher tack of this ink may 'lift' the coating from certain art papers.

    But I'll know more once we begin the trials.

    Does your company supply jumbo rolls of washcloth for auto blanket washers? Can I get a price for our Lithrone 626? It's 685mm wide.
     
    Poor housekeeping is the major cause of print defects and poor quality print. My opinion fwiw.
     
    Hi Richard, It will be interesting to find out the out come of your trial. TOYO have been banded around at least 3 different distributors in the last 2 years that I know of so may be there have been some issues. I`m not trying to put you off these inks by the way. They may well work out perfectly for your set-up.
    Regarding wash cloth, Yes we do the jumbo rolls & if I can have your company e-mail I will get some prices over to you.

    Cheers PC
     
    • I think a lot of people will be interested to hear your impressions and opinions of the Toyo Inkset. How did your trial go?
