Because you should ideally use the right tool for job.

You can, and plenty of people start off that way. It's just going to be more problematic.

Hi Joe

Short Answer: YES

The important thing in curing plastisol ink is to attain fusion temperature 280-320 degrees Fahrenheit, depending on the type of plastisol used.

Plastisol will start to become dry to the touch at 180-250 degrees Fahrenheit, which is what you do when you Print-Flash-Print (PFP) on multi-color jobs that require it.

Many screen printers use Flash-Cure units to fully cure shirts everyday. On your smaller conveyor dryers they use the same infrared heaters that are in the flash-cure unit.

The thing is to fully cure your ink, it might feel cured but if it doesn't reach fusion temperature it will probably crack or flake off when the garment is washed.

You will never achieve a high production output using a flash-cure dryer for curing your final product.

I hope this is of some help and good luck on your printing.
