The enamelled projection screen includes a substrate which is coated with at least one enamel layer which includes a pearlescent pigment and the gloss degree of which is between 1 and 40% on the 60° measuring head according to the ISO 2813 standard. This screen is manufactured by applying an enamel slurry on a substrate and burning it in at a high temperature, whereby, before the burning-in takes place, a quantity, preferably between 0.5 and 50 weight % in respect to the quantity of enamel in dry form, of a pearlescent pigment is added to the enamel slurry. The contents of pearlescent pigment are chosen sufficiently high and the temperature of burning-in sufficiently low in order to obtain the aforementioned gloss degree. |
