Prototype Dust Filter OOBE

Heated 5 minutes no cooling.


Backbone black plastic electronic housing goes in a cotton drawstring bag. It potentially sits under a pile of potatoes in a dusty environment. There’s an un-branded internal disposable sensor filter, too.


Double Drawstring Bag 6×10 inch natural color w/ Iron On Transfer Paper label.

Actual size 6 x 10 inch.



On the bag, the artwork alignment: Center the roof peak at about 3″ mark (halfway). The roof from the top of the bag is 3 to 3.5 inches and the text from the bottom is 2.5 inches approximately.

Final art is a mirror image for iron on about 4.25″x4.5″. Four-minute ironing with consumer iron. Print on textured side. Highest iron setting for cotton. Preheat iron for 5 minutes.

For production volumes, use a heat press.

  • Transfer Paper
  • Fully Machine Washable
  • Highly Durable (No Peel)
  • For Any Inkjet Printer with Any Inks
  • Heat Transfer Using Iron or Heat Press

Transfer Paper allows the transfer of high quality images, printed using an ordinary inkjet printer with ordinary inks, onto a wide range of fabric materials using heat such as t-shirts, bags, pillowcases, aprons, umbrellas and many others, using a domestic iron or heat press. As long as the material that you are ironing on can withstand the heat of the iron, you can safely transfer the design on to it.

Bags are a standard natural color linen or cotton and 6×10″. See attachment photo for dimensions. Also see the photo that shows approximately how much to allow for the material bunching at the top. We have to guess on the printable surface area. Reverse print from solid black is OK with me, too.

Anyway. A bag acts as a sensor dust filter. Black (one color) is preferred. Printed on one side of the bag.

The graphic element should gang 4-up (or more) on an 8.5 x 11 sheet to reduce individual bag printing cost. Then we cut them apart with scissors and iron on. The sheets are around $1 each. This reduces the per part cost to $0.25. Or maybe less. The bag is $0.54. Bags delivery is Thur OCT 24.

If quantity ever goes up, we’ll buy a heat press machine. But not yet.

Final art is a mirror image for iron on. Four-minute ironing with consumer iron. Print goes on textured side of sheet. Highest iron setting for cotton. Preheat iron for 5 minutes. Won’t come off when machine washed (we’ll see about that!)

We have a moderately junky inkjet printer here. The colors are never true. It should be good enough with black.
