International Classification:

B41J 201

US Classification:

347100, 347 95, 347 96, 347101, 347105

Abstract:

An ink jet ink set and recording element combination including A) a porous ink jet recording element having a 60Â specular gloss of at least about 5; and B) a pigment based ink jet ink set including at least two inks; wherein the RGD value is less than 40% and RGV value among inks is less than 10% when 60Â is used as the specular angle; the RGD and RGV values are calculated according to Equations (A) and (B), respectively: Where I is a variable which identifies a certain color patch used in the evaluation, N is the total number of color patches used in the evaluation.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 201

US Classification:

347100, 347101

Abstract:

A method of selecting a pigment ink set and receiver in combination including: printing at least two color inks onto a set of receiver to form single color patches of a Dmax density (100% dot coverage); measuring the gloss level of each patch and the receiver at a predefined specular angle; calculating the Relative Gloss Difference (RGD%) value of the ink set and receiver combination; and selecting the ink set and receiver such that RGD value is less than 40% when 60Â is used as the specular angle, and the RGD value is calculated according to Equation (A): where I is a variable which identifies a certain color patch used in the evaluation, N is the total number of color patches used in the evaluation.

US Classification:

347101, 347100, 106 3113, 106 316

Abstract:

A method of selecting inks within an inkjet ink set for color printing includes: a) providing at least two color inks, each ink having a carrier and a pigment; b) printing the above inks onto a receiver using test images consisting of single color patches of a Dmax density (100% dot coverage); c) measuring the gloss level of each patch at a predefined specular angle; d) calculating the Relative Gloss Variability (RGV) values of the ink set based on the definition in Equation A; and e) selecting inks for the color set such that the Relative Gloss Variability (RGV) among inks is less than 10% when 60Â is used as the specular angle: Where I is a variable which identifies a certain color patch used in the evaluation, N is the total number of color patches used in the evaluation.

International Classification:

B41J 201

US Classification:

347105, 347101, 428195

Abstract:

An ink jet printing method, including the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with ink jet recording elements with a support having thereon an image-receiving layer of a polymer having a given contact angle; C) loading the printer with an ink jet ink composition; D) printing on the image-receiving layer using the ink jet ink in response to the digital data signals to form an imaged recording element; and E) heating the imaged recording element sufficiently to cause the layer of polymer to increase the contact angle at least about 15 degrees.
