my navy blue ends up as purple

[Avalon]

Hello Guys, I wondered if anyone is able throw some light on this. Each time I print navy blue, it ends up as a purple/violet colour on the mug. I am using the Ricoh printer with paper and mugs supplied by TMT. I must add, that all the other colours seem fine with a fairly good overall print quality, except for the navy blue which thinks its purple. Any suggestions would be appreciated.

you printing via icc profile or powerdriver? can you give other more info ie time and temp you use?

Hi Paul, sorry was a bit vague - I am using Powerdrive with the sawgrass inks, Ricoh printer. The temp is 330f/165c and cooking for 120 seconds. These are the guidelines set from my cheapio chinese mug press, which seems to do the job ok ish although some colours could be a bit deeper.

I have a mug press and Ricoh 7700 using powerdriver and sawgrass inks all supplied by BMS. After some trial and error I settled on 170 degrees/50 seconds using BMS supplied mugs and always get really good colour transfer. I found some trial and error was needed....and a couple of calls to those helpful BMS folks sorted it for me. Hopefully this helps if not a call to TMT might solve your problems.

Good luck.

Thanks for your reply Roger, is that 50 seconds after the press reaching 170 degrees?
or inserting the mug in press to warm up to idle temp and then boost to 170 degrees and then a further 50 seconds ?
At the moment I am doing the latter at 30 seconds after my press hits 170 with the mug already warmed up sitting in the press during the idle temp mode. If you are suggesting the latter, then I should increase the time to 50? Sorry for confusing the issue , I am a newbie

I put a spare mug into the press when switching on then once up to idle temp set it to operate. Then remove the spare once the temp reaches around 160 and put the print mug in. This means the mat temp doesn't drop off too much with the 'colder' print mug going in and builds temp quickly back up to 170 when the timer kicks in. Once the time is up I dunk mine in warm water to stop any further subbing. It works good for me.

I have ricoh, i put spare mug in untill temp reaches 170 then put sub mug in for 140 seconds with firm pressure, perfect everytime.
I dont warm first and i dont dunk

Thanks for your replies everyone, I will try the various options for temp and time as suggested.

It may be simpler than that...

If you are using something like Coreldraw or Photoshop it is not uncommon for the Blue on the screen to print purple. Check the CMYK breakdown of your blue. If its 100 Cyan 100 Magenta then it will print purple. You will need to change this.

Socialgiraffe, very interested in what you say. Can you explain more? I've been subbing for years with both Epson and Ricoh printers, with and without Poerdriver. I find it really hard to get navy, I just assumed it was shortcoming of the sub process. I've looked at 3 of my often used tranfers with navy in them using PS. They're all high 90s if not 100 in magenta and cyan. What figures will print navy?

Cheers,

Michael
