Method for recording a digital image and information pertaining to such image on an oriented polymer medium

A method for recording an extended color gamut digital image on a hard-copy output medium having a limited color gamut comprising:

• a) providing the hard-copy output medium including biaxially oriented polypropylene;
• b) adjusting the extended color gamut digital image to be compatible with the recording properties of the hard-copy output medium;
• and
• c) recording the adjusted digital image on the hard-copy output medium;
• and
• d) producing a digital representation of information in the extended color gamut digital image which was not recorded in the adjusted digital image on the hard-copy output medium and recording the digital representation on the hard-copy output medium.

A method for recording an extended color gamut digital image on a hard-copy output medium having a limited color gamut, comprising:

• a) providing the hard-copy output medium including an oriented polymer;
• b) adjusting the color of the values extended color gamut digital image to fit within the limited color gamut of the hard-copy output medium to form a limited color gamut digital image;
• c) producing a limited color gamut output print from the limited color gamut digital image on the hard-copy output medium;
• d) determining a residual image representing a difference between the extended color gamut digital image and the limited color gamut digital image;
• and
• e) recording the residual image on the hard-copy output medium using a digital encoding means such that the residual image and the limited color gamut output print are adapted to be used to form a reconstructed extended color gamut digital image, whereby an improved image is provided on the hard-copy output medium.

A method for representing an extended color gamut digital image on a hard-copy output medium having a limited color gamut, comprising:

• a) providing e the hard-copy output medium including an oriented polymer;
• b) adjusting the color values of the extended color gamut digital image to fit within the limited color gamut of the hard-copy output medium to form a limited color gamut digital image;
• c) producing a limited color gamut output print from the limited color gamut digital image on the hard-copy output medium;
• d) determining a residual image representing a difference between the extended color gamut digital image and the limited color gamut digital image such that the residual image and the limited color gamut output print are adapted to be used to form a reconstructed extended color gamut digital image;
• e) storing the residual image using a digital storage means;
• and
• f) encoding information about the location of the stored residual image on the output print using a digital encoding means.

A method for representing and manipulating an extended color gamut digital image on a hard-copy output medium having a limited color gamut, comprising:

• a) providing the hard-copy output medium including an oriented polymer;
• b) adjusting the color values of the extended color gamut digital image to fit within the limited color gamut of the hard-copy output medium to form a limited color gamut digital image;
• c) producing a limited color gamut output print from the limited color gamut digital image on the hard-copy output medium;
• d) determining a residual image representing a difference between the extended color gamut digital image and the limited color gamut digital image;
• e) encoding the residual image on the output print using a digital encoding means such that the residual image and the limited color gamut output print are adapted to be used to form a reconstructed extended color gamut digital image;
• f) specifying a desirable modification to the image;
• and
• g) using the residual image together with the limited color gamut output print and the specified desirable modification to the image to produce a modified digital image.
