D-Base is a clear waterbase discharge ink. Suitable fabrics are easily discharged producing an extremely soft hand. D-Base can be used as a color-stripping ("bleaching") underbase or can be used with pigments. D-Base can be used in conjuction with other ink systems to produce multiple effects. D-Base's  flow characteristics allow it to be printed with high mesh counts. This produces very fine image detail and a softer finish. Don't forget 3-6% activator agent must be mixed in to this ink in order for the discharging process to occur! Once activator has been added, shelf life is around 6 hours so try to only mix as much as you need for your print job.

Preparation

Screens must be prepared with water-resistant emulsion to prevent stencil breakdown on press. Post-hardening the stencil is recommended for long print runs. Stir in 3-6% by weight, D-Powder Discharge Activator and mix well. Different percentages of the activator will yield different results. Mix only enough for current production requirements. Activated D-Base should be used within 8 hours of mixing. If using CMS pigments, you can add 1-10% pigment to the base depending on desired shade. D-Base may be thinned with water if a lower viscosity is required, up to 10% max.

Application

The screen mesh count being used will determine how much squeegee pressure should be used. Typically heavy squeegee pressure is preferred. Print wet-on-wet without flash curing. Occasionally lightly misting the screens with water during long print runs will help prevent drying in screen. The printed fabric should be cured for a minimum of 90 seconds at 320F degrees. Ideally the fabric should be. cured for 2-3 minutes at 340-350F. High volume forced air is recommended during curing. Do not allow the print to dry before curing in an oven the more moisture available, the better discharge result. Degree of discharging and color/wash fastness is dependent on proper curing. The activator will give off a strong odor, this is normal. Heat curing must be complete in order to assure the fabric does not retain the activator odor, re-curing may be required.

Clean-Up

General wash-up, on ink that has not dried up, can be done with water.
