1. Water ripple causes:
a. The printing plate is too deep.
b. The viscosity of the ink is low or excess diluent is added.
Solution:
a. Control plate depth during plate making.
b, control the ink viscosity.
c, using the wind or adjust the blade angle.
2. Biting causes:
a, ink slow dry.
b. The pressure of the second color is too high, printing is too fast and the viscosity is too high.
Solution:
a. Add a quick-drying solvent to the first color to increase the amount of hot air.
b. Reduce the pressure in the second color.
c. Reduce the viscosity of the second color ink and slow down the printing speed.
3. Adhesion (commonly known as anti-adhesion)
the reason:
a. The solvent is slow-drying (especially toluene contains volatiles and smells).
b. During the printing process, the rewinding pressure is too large and the stacking pressure is too large after printing (especially in high-temperature weather).
c. The temperature of hot air that is dried during printing is too high. Generally it should not exceed 40°C-50°C (if special requirements, cold wind should be added before rewinding to lower the film temperature), plus moisture (relative humidity greater than 90%) Above) The ink cannot be completely dried.
d. The electronic processing is too large (the standard 38 Dyne has already met the printing requirements). The single-sided printing, but the film is double-sided electronic processing, or the local treatment is too strong.
Solution:
a, replace the quick-drying and high purity solvent.
b. Adjust the winding tension so that the winding and pulling are synchronized. The stacking of the prints cannot be too high or the heavy objects are stacked on the surface.
c. The ambient temperature of printing sites and finished product warehouses should not be too high and there should be no heat sources and direct sunlight.
d. Single-sided printing is not used for double-sided electronic processing.
4. Reasons for starting from the top of the picture:
a. The pressure of the squeegee is small, the squeegee is too soft, and the printing plate is too thick on four sides to form a thick ink layer.
b, ink viscosity, impurities.
c. Static electricity is generated when the printing speed is too fast.
Solution:
a. Increase the knife pressure and replace hard blades.
b. Reduce the viscosity of the ink and filter the ink.
c. Install a static eliminator.
Bedroom furniture, sometimes called a bedroom set or bedroom suite consists of a group of furniture in a bedroom or sleeping quarters. Pieces of furniture referred to as bedroom furniture usually include: beds, wardrobes, dressers, chests, nightstands, armoires, vanities, trunks, and mirrors. There are also many variations of these pieces as furniture styles have changed through time and as individual manufacturers have put their own spin on them.
Bedroom furniture is predominantly made of wood, but many bed frames are made of various metals as well. Bed frames include but are not limited to bed rails, foot-boards and head-boards. Foot-boards and head-boards are usually made up of a few materials including wood, leather, paint & other various fabrics. Steel or iron is usually used for bed rails. Bed frames are most commonly built with support for a head-board.
Knock down fittings are usually used for locking in the bed rails and frames to the bed posts. Knock down fittings are very easy to take apart. A few types of knock down fittings include: Hook with pin fastener: mortise slots are cut in a vertical manner Hook with plate fastener: eye plates are used instead of pins.
