What is dot gain in inkjet printing?
Dot gain refers to a characteristic of halftone printing whereby reflectance of the printed material is less than would be expected from the percentage area coverage of the dots set on film by the imagesetter, or the percentage area coverage expected from a digital code value in the digital representation of the image.
What causes dot gain in printing?
Causes. Dot gain is caused by ink spreading around halftone dots. As printing pressure can squeeze the ink out of its dot shape causing gain, ink viscosity is a contributing factor with coated papers; higher viscosity inks can resist the pressure better.
How do you set printer ink on fabric?
Place the dry or lightly damp fabric onto an ironing board face up. Lay an equal size piece of parchment paper over the fabric. Set your iron onto high heat. Press the paper over the fabric for five to 10 seconds, moving the iron as needed until the entire fabric has been heated, setting the ink.
What is dot in printing?
It refers to ink dots appearing larger on the printed piece due to either a mechanical or optical effect. Dot gain is not good or bad. It is simply a normal result of the printing process that must be taken into consideration during the creation of the source file, the choice of papers, printing process, inks, etc.
Why is gray balance important?
Gray Balance is a significant factor in determining what the over all color gamut will be. Proper color reproduction at press can only occur when the press has achieved the same “gray balance proportions” as were present in the color separations.
What is dot gain scale?
Dot gain is a measure of the difference between the actual ink dot size of the printed piece and the ink dot size specified by the source file. It refers to ink dots appearing larger on the printed piece due to either a mechanical or optical effect. Dot gain is not good or bad.
What is Dot loss?
In prepress and printing dot loss refers to halftone dots either disappearing or reducing in size. Whereas some newspaper presses manage to maintain a 3% dot, there are screen printing presses in which any dot smaller than 15% simply disappears.
What is the main dot gain area in a printed image?
Is there dot gain in digital printing?
And inkjet papers always produce less dot gain than non-inkjet papers. To accomplish the job of image duplication, digital printing technology combines four systems into one integrated production process. Thus, an increased dot-gain value means a decreased print quality.
Is inkjet ink permanent on fabric?
Printer ink isn’t permanent on fabric, so to help set the ink into the fabric you’re going to give it a little vinegar bath. Place your sheet of fabric in a flat baking dish and pour in some white vinegar, just enough to barely cover the fabric.
Is inkjet printed fabric washable?
Generally fabric printed on inkjet printer is better not washed. But if you want to wash it hand wash the garment or machine wash on a gentle cycle in cold water and mild soap.
