Zusammenfassung:A memory device (108) for a printing device component, the memory device (108) comprising: compressed coefficients (110) that, when decompressed by a printing device, form difference entries, wherein a difference entry of the difference entries represents a difference of a value of a corresponding entry of a halftone table and a value of a corresponding entry of a reference table (122); and healing parameter values (114) specifying a healing process to apply to a reconstructed halftone table produced using the coefficients, wherein the coefficients and the healing parameter values (114) are accessible by the printing device to reconstruct a halftone table used in halftone printing by the printing device.
