Heat press help! (screened transfers)

(1/4) > >>

Hi Everyone,
i just started screening transfers, for inside neck labels, and i'm having a hard time getting it to cure properly.

I'm using a Hix B250D cap press, and i'm screening gray union ultrasoft ink, onto transfer paper i got from my local supplier.

Currently, my press is set at 365, and i've been heating it for about 8 seconds (i've done as few as 3, as many as 16 seconds), and i've tried hot and cold peel.

Right now they come out ok, although my smaller lines don't always come out clear, sometimes they look a little ragged. Also i just did a test wash on some fabrics, and they all washed out, so they are not curing right!

Any tips? anything i'm doing wrong?

Thanks!

Try

Go down to 350 and 20 or 30 seconds and cold pill.

See if that does it.

Frog:
You may also be over curing the transfer in it's initial run down the dryer. That then requires more of a melting when transferring.
You also may find a little help from the adhesive powder available from Union and others. It is applied either to the wet ink right after printing, or on the slightly tacky ink after its partial cure.

ericheartsu:
i put these transfers through a smaller dryer we have, at around 300 degrees. I'm going to try doing another set tomorrow at around 230 and see what happens!

From the Ultra Soft Tech Sheet

CURING OF HEAT TRANSFERS:

Prints on heat transfer paper (Trans-Lith, Trans-French and Trans-55) should only be semi-cured. Over-cure may cause problems later on during transfer (more energy is needed to remelt a cured film than a semi- cured film). Semi-curing or drying the film only to the extent that the sheets can be handled, stacked, cut and shipped is the desired condition. The ink will semi-cure when the ink deposit reaches 250°F (121°C).

TRANSFER TIME AND TEMPERATURE:

REGULAR TRANSFERS: Transfer at 350°F (177°C) for 20 seconds or 400 F (204 C) for 5 seconds at 40-50 p.s.i. Allow transfer to cool completely (10-30 seconds) before stripping off the paper. HOT-PEEL ULTRA SOFT TRANSFERS: Transfer at 375 F (190 C) for 10-20 seconds, or 400 F (204 C) for 5 seconds, at 40-50 p.s.i. Quickly strip the release paper IMMEDIATELY after raising the transfer press platen while the shirt remains in the press.
