1) Different color printers (ink-jet, color-activated, LED color-coded) differ in their product characteristics (printing language, consumables characteristics, imaging principles, etc.)
2) Even if the same device of the same brand uses different papers, the effect of the paper on the toner/ink adsorption is not the same;
3) Even if the same paper is used, the new machine state of the printing apparatus does not have the same effect on the color as the middle/end state of use.
Therefore, it is necessary to use ICC color management tools to periodically make ICC curves for different devices and different papers, and use the curves as compensation to calibrate the printer to an ideal condition.
After the ICC color curve calibration, the color accuracy of the printer can be improved to be closer to the original.
ICC color management application industry and customer groups
The main application and professional graphic industry:
Prepress (DTP): advertisements, publishing houses, newspapers, design institutes, medium and large size printing (DMC)
These professional image users have high requirements for color accuracy, so the standard color state of the device may not be able to meet their requirements, and ICC color management is required to more professionally calibrate the device.
A French press, also known as a cafetière, Ñafetière à piston, Cafeteria, press pot, coffee press, or coffee plunger, is a coffee brewing device patented by Italian designer Attilio Calimani in 1929.
A French press works best with coffee of a coarser grind than does a drip brew coffee filter, about the consistency of kosher salt. Finer grounds, when immersed in water, have lower permeability, requiring an excessive amount of force to be applied by hand to lower the plunger and are more likely to seep through or around the perimeter of the press filter and into the coffee. Additionally, finer grounds will tend to over-extract and cause the coffee to taste bitter. Coffee is brewed by placing the ground coffee in the empty beaker and adding hot-between 93–96 °C (199–205 °F)-water, in proportions of about 30 g (1.1 oz) of coffee grounds to 500 ml (17 US fl oz) of water, more or less to taste. The brewing time is about two to four minutes. The plunger is pressed to separate the grounds and hold them at the bottom of the beaker. The mesh piston normally does not compress the coffee grounds, as most designs leave a generous space-about 30 mm (1.2 in)-below the piston in its lowest position. If the brewed coffee is allowed to remain in the beaker with the used grounds, the coffee may become astringent and bitter, though this is an effect that some users of the French press consider desirable. It is believed that the optimum time for brewing the coffee is around four minutes, and some consider the coffee spoiled after about 20 minutes. Other approaches, such as cold-brewing, require several hours of contact between the water and the grounds to achieve the desired extraction.
