Re: new toys here at last

Glad that someone else has started to experiment as well! Let me share my film cases here.
I've done 3 so far.
Case 1: 90 C for film and 190 C for press, total time of 360 seconds with 20 second delay
Case 2: 90 C for film and 190 C for press, total time of 420 seconds with 20 second delay
Case 3: 90 C for film and 160 C for press, total time of 300 seconds with 20 second delay
Here's the result of Case 1 and Case 2. With the leftmost case being a case pressed with paper and the old machine, then case 1 and rightmost is case 2.

At 190 C and those times, it's way over done. And the film wraps and stretches and creates the curved line...No good...
Here's the result for case 3, the right hand side case. Left hand side is the paper-pressed case.

The result is significantly better than the former cases although the color is noticeably brighter in the paper-pressed case...And I still have two issues:
Grainy picture and rough borders (this is not the camera's graininess). Left picture is case 3 and the right picture is paper-pressed case:

In the old machine, it looks like the symptom of the paper shifting during press.
The other issue is the weak transfer on the side. You can probably tell which case is which judging from the corner and the color. The darker one is the paper-pressed case. And if you can zoom on the picture, it shows how the film-pressed is grainier and the border with the black line is fuzzier.

I haven't tried 120 C as Justin suggested since I though regular sublimation ink only transfers at 190 C or above...
I will test my regular ink at 120 C and if that's unsuccessful, I will try the low temp sub ink.

Regarding fumes/smell do you notice less of this when decreasing temp? Considering getting a vacuum press but bit concerned about the melting plastic fumes I assume is generated by cases and film.. Guess an extractor fan of some sort will be needed.
