Dear Amornrut,
Thank your for your request.
When the two anilox rollers are hexagonal gravured, then are 60 lines per cm a lot of transfer (17 cm³/m²)
and 100 lines per cm (11 cm³/m²) often enough too.
In February 2016 when we visited them they changed to a other cardboard. After that they had a great result with
one run. Is it possible that they change the cardboard or the coating plate again?
In the most cases is one run absolutely enough, only sometimes when the substrate is very uneven or absorbent,
customers need two runs.
Sometimes too much hot air cause an uneven surface, Senosoft drying very fast. They can reduce the hot air 20-30%.
Senosoft 350210 FP NDC with activator is the right product.
I recommend to visit them in February and run a test or a production together with R-Pac to achieve a good result again.
They should have some different soft coating blankets/ Plates and as option another cardboard too.
I´ve seen our conversation from October attached to this mail. There are still stripes visible?
Then is the anilox roller dirty, damaged or the blades are not in a good condition.
