Bulb Needed To Burn A Silk Screen? (Screen Printing)?
Hi There, I Am Having Real Difficulty In Finding A Good Enough Bulb To Burn My Silk Screen And Also A Bulb Holder To Hold Such A High Wattage! It Calls For A 250W Photoflood Bulb But These Seem To Be Discontinued And I Cannot Find Them Anywhere, If I Found One It Was Going To Be Held In A Ceramic Bulb Holder With A Max Wattage Of 250, Meaning That The Latest 275W Bulbs Are Not Suitable. I Came Across A Bowens Halostar 250W Bulb And Wondered If This Would Be Suitable? Its Shape Is Quite Strange So I'M Not Sure If The Light Would Be Too Concentrated In One Area, Even With The Use Of A Reflector. Does Anyone Have Any Experience With This? If You Can Advise Any Other Bulbs That Would Work That Would Be Great. I Don'T Want A Halogen Work Light Though Or An Exposure Unit. I Also Live In The Uk. Thanks For Any Responses.

When I was burning emulsions for screen printing, I just got a "sunlamp" bulb in a short stand. The selection for UV lamps/bulbs/sources is even wider nowadays I would guess...here's what one guy said as possibilities:

. . . sunlight, un-filtered black lights, quartz, mercury vapor and metal halide lamps (of course some sources work better than others, and like computers faster usually means more money)

Good luck!

Which Is Better Silk Screen Printing, Vinyl Cutting Or Iron On Transfers?
Which Do Big Clothing Line Companies Use ?

All three applications have their place and are all used by big clothing companies. Do you have any shirts with a tag-less label? That's most likely a heat transfers.

The size of the company has little to do with which method they employ. The project dictates the decoration method. Traditional direct screen printing is used for printing a few dozen all the way to millions of units. Cutting vinyl is great for creating a one of kind image for one-off customization or personalization. You can have heat transfers screen printed to help manage inventory, decorate heat sensitive items, or press shirts live at an event.

As far as quality is concerned all can be employed properly and wash and last the life of the garment. A novice screen printer and under or over cure the plastisol ink impacting washability. The application of a vinyl or a screen printed heat transfers can also be done improperly (using incorrect time, temperature or pressure) affecting the print quality.
