Ink Residue
Hi all 😛 I finally bought a sublimation mug press and it’s a good one as well, but having a small issue with it….. wouldn’t you guess…lol
anyway i have tried various settings and at the moment i have them set at
190 stand by
200 heat
80 secs time out
here’s the issue, i keep getting residue ink left behnd by the last mug, lots as well. we never had this with previous mug presses and never at Uni
thing is when the machine is at stand by temp and I slap a mugin it goes right down and then takes an age to come back up to the working temp for the countdown to begin..
where am i going wrong

Usual question, what make is it? Mine does not have a stand by function.
Are you using a blow out sheet to stop ink escaping. -
its a DFS 180 dunno where my dad got it but it’s brand new, cost £300
i am using a teflon sheet and thats where the ink is coming from, i do onemug, then even i do another two days later i still get remnants of a previous mugs design. like on Friday when i got home i did a mug of my dog, then this morning did one of my cat, and my cat one has some words from my dog one,you can just see them but they are there. When i say stand by i mean idle tempreture. we tried it at 90c but when you put a mug in it goes right down to 50c and then takes ages to reach 200c andthen i originallyhad it set at 3 mins, now it’s 80 seconds. 😳

You should be using a blowout sheet, which is just an ordinary piece of paper cut to the size of the mug this will stop the ink getting onto your teflon sheet, use a fresh one for each mug.

If you have a DF180 then don’t set the idle temperature to 190. You will blow the blanket and then spending more money getting a new blanket. The idle temp is set low so that when the blanket is heating up without a mug in place it doesn’t get too hot. When the mug goes in and the clamp engaged then it will heat to the operating temp (180/ 190 degrees recommended).
All the blankets will loose heat when you put a mug in – the mug is a lot cooler than the temperature of the blanket and so the heat of the blanket gets absorbed into the cooler mug. The press should then re-heat the blanket and the mug to get to operating temp. With the DF180’s you may find that if they take a while to get back to the operating temp then the actual press time can be reduced – you’ve reduced it to 80 seconds already and it might go lower depending on your preferences. But, whatever you do, don’t keep the idle temp at 190 – no mug press should be allowed to heat up that high without a mug in the machine or the blankets will get hot spots and could burn out.
I agree with Gordon about the silicon/ blow out sheets, but you may find that the paper you’re using is allowing some of the ink to come back through the paper and leave a slight imprint on the heat blanket. This is then being transferred back to the mug next time.

thanks but still having issues
took the idle down to 90
temp overall to 190
it took 3 minutes to reach op tempreture, surely this is too long??
took time down to 70 secs,
4.10 to do a mug?? and now i am back to having a jagged light edges,, not good.
have taken the idle time back up to 140, overall to 190 and see how i go.
beginning to think me and mug making is not a good idea, recieved a warning from my dad as well that if i bust this i’m for the high jump, lol

Don’t know about the idling temps but I would think the mug needs to go in when the element has heated to the 190. Fair enough leaving the temp low if a mug is not going to be printed but you need to find a consistent temp for when you start the printing process. The press usually drops by about 50c when putting in a cold time and then rises back up and might be at full temp for not much more than 30/40 secs.
