Variable data printing method using variable text color depending on background
An improved variable data printing (VDP) method is disclosed. A VDP database contains variable data and form data. The variable data includes a plurality of entries each having a plurality attributes. The form data includes images. Each printed piece of a VDP production includes variable data and form data selected based on the variable data attributes. When the printed pieces include a background image and foreground text to be printed over the background image, and when different pieces in the VDP production have different background image, the method automatically selects a text color to print the foreground text over the background image on each piece to enhance visibility and/or aesthetic appearance. In addition, the foreground text color for each piece may be selected based on additional attributes of the variable data.
1. A variable data printing (VDP) method implemented in a data processing apparatus, comprising:
(i) receiving VDP data including variable data, form data and a plurality of association rules from a VDP database, the variable data including a plurality of entries each having a plurality of attributes, the form data including a plurality of background images, the association rules defining associations between variable data attributes and form data;
(ii) for each entry in the variable data,
(a) obtaining a color association rule as a separate file from the VDP database specifying a foreground text color for each background image in the form data;
(b) obtaining at least one attribute;
(c) selecting a background image from the form data based on the at least one attribute;
(d) selecting a foreground text color based on the background image obtained in step (c) and the color association rule for printing text over the background image; and
(e) generating an image based on variable data and form data selected using the association rules and based on the foreground text color determined in step (d), the image including the background image and foreground text in the foreground text color over the background image.
2. The method of claim 1 , wherein the foreground text color for each background image in the color association rule is determined automatically by a computer.
3. The method of claim 1 , wherein the foreground text color for each background image in the color association rule is determined manually by a user.
4. The method of claim 1 , wherein step (b) includes obtaining at least two attributes,
wherein in step (c) the background image is selected based on a first one of the at least two attributes;
wherein step (d) includes:
(d1) selecting a plurality of candidate foreground text colors based on the background image selected in step (c); and
(d2) selecting one foreground color from the plurality of candidate foreground colors based on a second one of the at least two attributes.
5. The method of claim 1 , further comprising printing the image generated in step (e).
6. A computer program product comprising a non-transitory computer usable medium having a computer readable program code embedded therein for controlling a data processing apparatus, the computer readable program code configured to cause the data processing apparatus to execute a variable data printing (VDP) process, the process comprising:
(i) receiving VDP data including variable data, form data and a plurality of association rules from a VDP database, the variable data including a plurality of entries each having a plurality of attributes, the form data including a plurality of background images, the association rules defining associations between variable data attributes and form data;
(ii) for each entry in the variable data,
(a) obtaining a color association rule as a separate file from the VDP database specifying a foreground text color for each background image in the form data;
(b) obtaining at least one attribute;
(c) selecting a background image from the form data based on the at least one attribute;
(d) selecting a foreground text color based on the background image obtained in step (c) and the color association rule for printing text over the background image; and
(e) generating an image based on variable data and form data selected using the association rules and based on the foreground text color determined in step (d), the image including the background image and foreground text in the foreground text color over the background image.
7. The computer program product of claim 6 , wherein the foreground text color for each background image in the color association rule is determined automatically by a computer.
8. The computer program product of claim 6 , wherein the foreground text color for each background image in the color association rule is determined manually by a user.
9. The computer program product of claim 6 , wherein step (b) includes obtaining at least two attributes,
wherein in step (c) the background image is selected based on a first one of the at least two attributes;
wherein step (d) includes:
(d1) selecting a plurality of candidate foreground text colors based on the background image selected in step (c); and
(d2) selecting one foreground color from the plurality of candidate foreground colors based on a second one of the at least two attributes.
