  • the image consisted of adjacent patches of cyan, magenta, yellow, black, green, red and blue patches, each patch being in the form of a rectangle 0.4 cm in width and 1.0 cm in length. Bleed between adjacent color patches was qualitatively assessed. A second image was printed, and immediately after ejection from the printer, the image was wiped with a soft cloth. The ability of each recording element to dry quickly was qualitatively assessed. Results are shown in Table 3. Recording Element Image Quality Dry Time 1 Little bleeding Instant 2 Little bleeding Instant 3 Little bleeding Instant Comparative 1 Considerable bleeding Instant Comparative 2 Considerable bleeding Instant
  • the above table shows that the recording elements of the invention have good image quality and instant dry time.
