Question regarding high-gloss printing on baryta paper.
I am only achieving an irregular gloss finish, which is always similar, despite varying conditions and the two different papers I have available: Foma and Classics from FOTOIMPEX.
PROBLEM: In some places (20%), scattered across the entire print (format: from test strips up to 30x40), the indentations of the untreated surface texture appear as islands amidst the good gloss. This is probably not to be confused with dot formation, is it? The print also comes away from the film on its own, without mechanical resistance.
Regarding the temperature of my antique press: I have a dimmer fitted upstream, which allows me to vary the press temperature
between 50–110 °C (measured on the plate (without high-gloss film)).
I have tried all settings!
As a wetting agent, I use Mirasol from Tetenal (tried various dilutions) and also washing-up liquid mixed with distilled water.
Possible causes could be:
- too much water squeezed out, which is presumably needed for the melting process.
- temperature too low for the melting process
- Temperature too high, causing the water to evaporate too quickly and thus preventing the melting process.
Regarding the temperature of my antique press: I have a dimmer switch fitted, which allows me to vary the temperature of the press
between 50–110 °C (measured on the plate (without high-gloss film)).

Hi Thomas,
Try placing the damp paper on the high-gloss film and rolling firmly over it with a roller to remove any excess water before you place the print on the hot press.
That should do the trick!

Hi Walter,
Thanks, I’ll try squeezing the water out again using a bit more pressure.
Best regards,
Thomas
