Ink Blow Out

[snjokaggl]

Simple cure, bin it, buy a Ricoh, headache gone.

Second that! The Ricoh is amazing!

Thanks for the replies. What type of window cleaner do you mean?
Does anyone think that the use of 'black point compensation on photoshop output to the printer driver' makes any difference
The problem doesnt just occur on lettering but on the photos as well where there are any light areas.

Black Point Compensation won't make any difference to this issue.

The only way I've "solved" it on my 1400 is to change the text to be deep blue (about 90% or so). It still looks dark enough to be black when printed, but because no black is used there is no blow out/spray.

Another option when doing mugs is to use mugs from BMS. I'm using some now after using Revolution ones for ages. The BMS mugs have the "advantage" of not being bright white - so the dusty blow out from the black is far less noticeable than it is on a bright white mug.

Sorry that these aren't definitive solutions, but they are what's worked for me so far.

The green windiwcleaning sprey that comes in a gun for about £1 us a brilliant solvent for inkjet ink.
At first sight of dirty marks we sprey a sheet of blotting paper and print onto it, or you can use the expensive no tear kitchen towels too.
Used this method on wide format printers for 10 years, it's a great trade secret.
Our bulk ink d88 started black spreying, we were told that was it.... We bought a richo and never regretted it but we do wonder hiw gel ink will perform in cold weather?
In a market situation will it still flow at close to 0c? The d88 was fine regardless of temperature.

hi, i have just joined because i am getting this. i use paper that is 135g and mugs from bms, i have not changed a thing, other than i am using a new mug blanket also from BMS. I am getting this on every mug ...a lot, have tried changing the heat settings but this is has now got me beaten. thing is my mug machines heat plunges by 80 when i put it in the press. currently i have got it better than it was but i am heating it up to 245............ this plunges to 175 it takes about 30 secs, then takes another 2 mins to creep up to 250, followed by 30 secs to time out, making 3 mins. i don't know what to do as i make mugs with my family as a hobby and we don't want to waste mugs and paper and ink.

could it be heat?

could it be ink?

i'm not to sure about the heat or ink as wekeep old prints that are on different paper and printed a while ago, plus new prints, same result, drips at the bottom of the mugs and its worse with the colour Blue

help please

A few quick comments...

245 is way way too hot. Heating your blanket to this temp can cause damage. You only need 180 for mugs.

135g paper? Why so thick? This may cause crease marks when wrapped around mugs resulting in a blow out of ink.

Temp drops when you put mug in? To be expected especially from 245 degrees. Mugs are cold, blanket very hot so heat sinks into the mug causing the blanket to drop in temp.

Martin this is Bryan, Me and Jon today put a new blanket in, we've always used the same settings. what do you suggest we try? the paper doesn't crease. Also the new blankets are pinky white inside?? is this usual for the DF-180, we always had shiny bblack before

we've been pulling our hair out all day and as you know Jon gets easily upset. so i have been helping him (or trying to)


tell me what to try with heat settings?

we always use a rubbish mug for a while to get any ink still on the blanket and then let the machine creep up to the tempreture before putting in a mug. would you suggest we warm the mugs up? we have tried before but Jon had issues burning himself, but we could try.

the paper is 135g because i was getting it from a guy on ebay, we had issues with his 130g and moved upto 135g on his advice, it's brilliant paper never had an issue with it and with Jon its better to have something a bit more robust.

i would appreciate any help as you know we only do this as a hobby, although extremely expensive for me.
