Hello guys!
I found this great forum and I come to you because I´m having some issues sublimating metal boxes in the vacuum machine.
The problem is that some little spots, stains and kind of strands appear when sublimating. As you can see in the images it also happens that colours are not vibrant, blacks are not deep and there is a kind of grain/noise mainly in the darker sides.
I explain the process I do so maybe you can help me.
I use a Sublimation machine + Epson FF100 / 170 + Silver sublimation film
The configuration is:
- Photoshop manages colors
- Epson Sc-f100 series generalpurpose profile (rigid)
- DS transfer paper type general purpose/metal
- High quality
- In the color settings, in the workspace I have set RGB: sRGB IEC61966-2.1, in CMYK I have set U.S.WEB COATED (SWOPP) v2 and in gray and spot ink I have set "Dot gain 15%". In the color management rules I have put "Preserve embedded profiles" in the RGB, CMYK and GRAY dropdowns.
I did some color adjustment to find more contrast and color push and finally I converted into sRGB IEC61966-2.1. This way I achieved better definition than before in Silver Sublimation Film (just in case it helps to anyone). It took a while...
SUBLIMATION:
I set the pre warming in 60 seconds
Temperature - 130 ºC
Time - 240/270 seconds. (I have tried this frame but it always happens more or less the same)
Vacuum pressure: It starts going up to 9 and in some seconds it goes down to 8 and stays there until the end.
When I open the vacuum machine I take off the film and I leave the metal top of the box in a safe place so it can cool.
Basically pre problems are:
- White Stains, dots, threads on sublimation (They're not in the print)
- No deep colours. Everything feels like a bit washed.
- Grain. Particularly in darker places.
Hope I have explained everything well.
Thanks in advance for your helps mates. Maybe with your help I can make these works properly.
Have a nice day!
