Conversely, spread enlarges the white layer to ensure complete coverage underneath the colored inks, preventing gaps or thin spots. The optimal choke and spread settings depend on the specific design, fabric type, and printer settings. An example of choke and spread adjustment is when you are printing a black line on red clothing, the choke can ensure that the red does not look like its bleeding through the black line.
-
White Ink Density Control
The RIP software controls the density of the white ink layer, determining how much white ink is deposited in a given area. Higher white ink density results in brighter and more opaque colors, while lower density reduces the amount of ink used and can create a softer, more vintage look. The optimal white ink density depends on the desired aesthetic and the opacity of the colored inks. A higher density is often required for dark fabrics to achieve vibrant colors, while a lower density may be sufficient for lighter fabrics or designs with transparent elements.
-
Selective White Application
RIP software allows for selective application of the white layer, enabling users to specify which areas of the design require a white underbase and which do not. This is useful for creating designs with intentional transparency or for printing on garments where certain areas are meant to show the fabric color. For example, a design with a distressed or faded effect may require selective white application to allow the fabric color to show through in certain areas, creating a more natural and authentic look.
