Abstract
Method for printing pages within a booklet to improve the appearance of images on opposing pages includes sequencing images such that opposing pages are printed with the same print engine and/or fused the same number of times. Booklets include opposing pages having images fused the same number of times and/or printed with the same print engine as the image on the opposing page.
Claims12
A method for producing a booklet from a multiple engine serial duplex printer, comprising:
- ordering sequentially a first plurality of images on a first printing device;
- feeding sequentially a plurality of two-sided sheets to the first printing device;
- printing sequentially on one side of each of the plurality of two-sided sheets a corresponding one of the first plurality of images;
- ordering sequentially a second plurality of images on a second printing device, such that when the second plurality of images is sequentially printed on a corresponding one of the other side of each of the plurality of two-sided sheets and alternate sheets in the sequence are inverted and stacked with alternate non-inverted sheets, images on opposing sides of the sheets are printed by the same printing device;
- feeding sequentially the plurality of two-sided sheets to the second printing device;
- printing sequentially on the other side of each of the plurality of two-sided sheets a corresponding one of the second plurality of images;
- inverting alternated ones of the plurality of two-sided imaged sheets;
- and
- stacking sequentially the inverted sheets and non-inverted sheets, so that images on opposing sides of the sheets are printed by the same printing device.

A method for producing a booklet from a multiple engine serial duplex printer, comprising:
- ordering sequentially a first plurality of images on a first printing device;
- feeding sequentially a plurality of two-sided sheets to the first printing device;
- transferring sequentially on one side of each of the plurality of two-sided sheets a corresponding one of the first plurality of images;
- fixing the image marked on each sheet;
- ordering sequentially a second plurality of images on a second printing device, such that when the second plurality of images is sequentially fixed to a corresponding one of the other side of each of the plurality of two-sided sheets and alternate sheets in the sequence are inverted and stacked with alternate non-inverted sheets, images on opposing sides of the sheets are subject to the fixing process the same number of times and are printed by the same printing device;
- feeding sequentially the plurality of two-sided sheets to the second printing device;
- transferring sequentially on the other side of each of the plurality of two-sided sheets a corresponding one of the second plurality of images;
- fixing the images marked on each sheet, the images corresponding to the first plurality images being fixed a second time and the images corresponding to the second plurality images being fixed a first time;
- inverting alternated ones of the plurality of two-sided printed sheets;
- and
- stacking sequentially the inverted sheets and non-inverted sheets, so that images on opposing sides of the sheets are subject to the fixing process the same number of times and are printed by the same printing device.

A method for producing a booklet from a recirculating duplex printer, comprising:
- ordering sequentially a first plurality of images on a printing device;
- feeding sequentially a plurality of two-sided sheets to the printing device;
- transferring sequentially on one side of each of the plurality of two-sided sheets a corresponding one of the first plurality of images;
- fixing the image marked on each sheet;
- inverting sequentially a first pass of each one of the imaged plurality of two-sided sheets;
- ordering sequentially a second plurality of images on the printing device, such that when the second plurality of images is sequentially fixed to a corresponding one of the other side of each of the plurality of two-sided sheets and alternate sheets on the second pass in the sequence are inverted and stacked with the alternate second pass non-inverted sheets, images on opposing sides of the sheets are subject to the fixing process the same number of times;
- feeding sequentially the plurality of two-sided sheets to the printing device;
- transferring sequentially on the other side of each of the plurality of two-sided sheets a corresponding one of the second plurality of images;
- fixing the images marked on each sheet, the images corresponding to the first plurality images being fixed a second time and the images corresponding to the second plurality images being fixed a first time;
- inverting alternate ones on the second pass of the plurality of two-sided printed sheets;
- and
- stacking sequentially the inverted sheets on the second pass and the non-inverted sheets on the second pass, so that images on opposing sides of the sheets have been subject to the fixing process the same number of times.
