What information do you have on how to handle inks that affect mirror effect?

Be sure to stir mirror inks before printing. Some of the components may be separated, but stirring will make them uniform. Insufficient stirring may cause streaking or unevenness.

Do not return ink to the container of unused ink after printing. Ink remaining on the stencil will cause aluminum to agglomerate with each other, and printing again may cause a decrease in mirror effect quality, as well as the occurrence of streaking and unevenness. The above problems may occur if used ink is used, so please avoid using used ink.

Regarding the supply of ink, it is more efficient to use ink by pouring ink little by little onto the stencil than to put the amount of ink required for printing on the stencil at once.
