The quality of advertising signs depends on the post-treatment process

One of the tricks: as far as possible, choose the three-dimensional engraving (some say: two-dimensional and half engraving) scheme for engraving, and choose a 90 degree conical knife for engraving, so as to visually weaken the roughness on the engraving surface of the fiber plate.

Tip 2: when setting engraving, do not perform layered engraving. Set it to the best depth at one time, which can be achieved by changing the tool. This is because there will be overlapping marks after layered carving, which will affect the smoothness of the carved parts.

Tip 3: since there are instant stickers on the surface of the workpiece before engraving, it is safe to operate when filling. Directly use the brush to fill the color manually, saving paint and labor, and the effect is not bad.

Tip 4: when using self painting for color filling, spray the color paint in a paper cup and let it stand for 15 minutes, and then dip the brush into the color for filling. Otherwise, the highly corrosive thinner in the self spray paint will damage the paint surface of the workpiece.
