It can be used as an undercoat or overcoat, making it a useful addition to the darkroom for photographers who coat their own papers and other materials.\u003c\/p\u003e\r\n\r\n\u003cp\u003eApplied as a basecoat to highly absorbent surfaces, Colloida C helps reduce the amount of photographic emulsion needed. It can also be used with ready-made liquid photographic emulsions and as a gloss aid when drying fibre-based photographic paper with a heated print dryer.\u003c\/p\u003e\r\n\r\n\u003ch4\u003eWhy We Like It\u003c\/h4\u003e\r\n\r\n\u003cp\u003eColloida C is a practical way to prepare absorbent surfaces before applying photographic emulsion. By creating an undercoat, it can help you make better use of your emulsion, particularly when experimenting with handmade photographic papers and alternative surfaces. We also like that it has a second use as a gloss aid for fibre-based prints.\u003c\/p\u003e\r\n\r\n\u003ch4\u003eIdeal For\u003c\/h4\u003e\r\n\r\n\u003cul\u003e\r\n\u003cli\u003ePreparing absorbent surfaces for photographic emulsion\u003c\/li\u003e\r\n\u003cli\u003eUndercoating or overcoating photographic emulsions\u003c\/li\u003e\r\n\u003cli\u003eWorking with ready-made liquid photographic emulsions\u003c\/li\u003e\r\n\u003cli\u003eHand-coated photographic papers and experimental darkroom projects\u003c\/li\u003e\r\n\u003cli\u003eImproving the gloss of fibre-based prints when using a heated print dryer\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch4\u003ePrepare Surfaces Before Coating\u003c\/h4\u003e\r\n\r\n\u003cp\u003eColloida C can be applied as an undercoat to highly absorbent materials.
