Technical Information for Excalibur® 998 Series

Sublimation Lithographic Printing and Production: Sublimatin Litho Inks perform on the press like conventional lithographic ink. For best results and color control, process work should be run on a four-color press, although satisfactory results can be obtained on a single or two color presses. It is also possible to utilize a web press, provided the web is sheeted at the delivery end. When the inks are initially printed on the paper, they appear dull and dirty. It is only after they are heat transferred onto the material that the true color develops. Color bars must be run and densitometer readings taken to ensure even coverage on the sheet. Slight variations in inking result in large differences when the transfer is made. For proper quality control of the printed paper, it is absolutely essential that the lithographer have a heat transfer press to test the color. There is no way that the color on the paper can be related to the color on the fabric unless the transfer print is made. Sheets should be checked at least every 500 impressions. Anyone who is unwilling to make this minimal investment should not consider entering the field of sublimation printing.Sheets must be checked for scumming and tinting. Any defects will be transferred from the non-image areas.

Release Paper: ST88 is recommended though most types of offset paper can be used. Coated stock is not recommended.

Transfer Properties: This type of transfer works well on polyester blend fabrics i.e. T-Shirts, mouse pads, pennants, etc. They can also be applied to specially coated materials including: ceramic, wood, plastic and metal.

Transfer Method: Time, temperature and pressure will vary according to the type of material being transferred.

Time, Temperature and Pressure Settings:

Important: *For garments - preheat to remove moisture. Use Teflon sheets inside shirt to prevent ink blow through. **Time and temperature vary with press.
