Sodium alginate printing paste can mean a hydrated stock thickener or the complete working color paste. Neither should be confused with the dry alginate grade being purchased. Record powder dose, stock concentration and stock addition separately: dilution with dye solutions and auxiliaries changes the final alginate concentration. Approve preparation and filtration first, then test the complete reactive-printing paste through the intended screen, fixation and wash-off process.<\/p>\n\n\n\n

Keep a Powder, Stock and Working-Paste Concentration Ledger<\/h2>\n

Use a mass basis and state whether the powder is measured as supplied. For a simple stock made only from powder and water, stock concentration is powder mass divided by final stock mass. Final powder-equivalent concentration is stock mass added multiplied by its powder mass fraction, divided by final working-paste mass. This is not automatically active-polymer content.<\/p>\n

Illustrative arithmetic only: 400 g of a 4% w\/w powder-as-supplied stock contains 16 g powder equivalent. If the completed paste weighs 1,000 g, its powder-equivalent concentration is 1.6% w\/w, not 4%. These values illustrate concentration arithmetic, not a recommended dose. Account separately for any additional thickener, dilution or material loss.<\/p>\n\n
Observation<\/th>Check before changing grade<\/th>Verification<\/th><\/tr><\/thead>
Lumps or high filter residue<\/td>Powder feeding rate, wetting, mixing geometry, water quality and hydration history.<\/td>Repeat preparation with one controlled change; identify retained material rather than calling all residue insoluble alginate.<\/td><\/tr>\n
Stock is repeatable but working paste changes<\/td>Final concentration ledger, dye solutions, auxiliary additions, pH and paste age.<\/td>Compare the stock and complete paste separately at matched test conditions.<\/td><\/tr>\n
Viscosity readings disagree<\/td>Temperature, instrument, spindle, speed, container, immersion and measurement timing.<\/td>Repeat using an agreed method and suitable instrument operating range.<\/td><\/tr>\n<\/tbody><\/table>\n

The Brookfield DVE operating instructions<\/a> identify measurement settings and sample history as relevant controls. A reproducible viscosity reading still requires a printing trial; it does not by itself prove screen release, pattern definition or wash-off.<\/p>\n<\/section>\n\n\n\n
