- the print job also includes the print environment data shown in FIG. 2, and the layout information thereof includes, for example, whether or not each page is skipped (Skip) and the number of prints (Print), as shown in FIG. Contains information.
- FIG. 9 shows an example in which the number of pages P of the print data is “3” and the number of slots S of the print template is “4”. In the example of FIG. 9, the number of printed sheets of the first page and the third page is set to "1", the number of printed sheets of the second page is set to "2", and the skip page is set to none.
- the first page (Page 1) is inserted into the first slot (Slot 1) of the print template. Is assigned, the second page (Page2) is assigned to the second slot (Slot2), the second page (Page2) is copied and assigned to the third slot (Slot3), and the third is assigned to the fourth slot (Slot4). A page (Page3) is assigned.
- FIG. 11 is a flowchart showing such a multi-page / single layer allocation process.
- the page number p and the slot number s are set to the initial value "1" (step S31).
- the print data of the p-page is allocated to the s slot (step S34).
- the slot number s is updated (step S35), and the process ends when the slot number s exceeds the number of slots S (step S36), but if the slot number s does not exceed the number of slots S, the first page is specified by Print.
- step S37 It is determined whether or not the allocation for the number of sheets has been completed. If the allocation of the specified number of sheets has not been completed, the calculation returns to the calculation of the print slot position from step S33, but if the allocation of the specified number of sheets has been completed, the page number p is updated (. Step S38). When the page number p exceeds the number of pages P, the process ends (step S39), but if the page number p does not exceed the number of pages P, the process returns to step S32 for determining whether or not the skip designation of the first page is specified. If it is determined in step S32 that there is a skip designation for the p-page, the process for updating the page number p (step S38) is performed.
- the print data to be allocated is multi-paged and stored in the hot folder 11, and the allocation process is executed according to the print environment data. Therefore, it is necessary to allocate the print data of each page. There is no. Further, since the print data is assigned to each print slot based on the jig layout information, the position of the object to be printed and the print position do not deviate from each other.
- whether or not to skip the page is specified, but it may be possible to specify whether or not to skip the use of the print slot.
- the information of the print slot to be skipped is specified in advance as the skip slot information in the layout information. Then, based on the skip slot information, it is determined whether or not the s slot is skipped before or after step S32 in FIG. 11, and if there is skip, the process proceeds to step S35 to update the slot number s. If there is no skip, the allocation process for the s slot may be executed.
- the corresponding print slot 16 can be used from the input unit 14a. Can be specified to skip the allocation of pages to the print slot 16.
- the above multi-page data can also be created from print data of a plurality of single pages and single layers.
- FIG. 12 shows an example of creating multi-page single-layer print data by nesting two print data (Job1 and Job2).
- the "nesting process” is a function of processing a plurality of print data (print jobs) into one, and each printing so as to eliminate wasted space when the plurality of print data are combined into one. It is a process including a function of adjusting the arrangement of data.
- the layout information when the layout information is set, the allocation process according to the layout information is prioritized. Therefore, in the "nesting process” described here, only multi-page conversion is performed by integrating the print data, and the layout of the print data follows the layout information.
- Such nesting processing may be performed by the print data generation device 20 or by the editing operation of the print job in the raster image conversion device 10.

- Multi-page / multi-layer printing For example, when performing thick printing with UV curable ink on a transparent smartphone case, white ink is printed on the entire surface as a base layer, and an image with CMYK ink is printed on it. On top of that, multi-layer printing may be performed, such as thick printing using burnish ink.
- multi-layer printing by a multi-pass printing method in which the inkjet head is reciprocated in the sub-scanning direction by the number of printing layers on the table (platen) of the inkjet printer 30 will be described with an example.
- the print data for performing the multi-layer printing as described above is also input as the multi-page data.
- FIG. 14 shows an example of multi-page and multi-layer print data to be input.
- This print data includes image data of three pages corresponding to each of the three layers constituting one image.
- the first page is image data for printing white ink
- the second page is image data for printing CMYK ink
- the third page is image data for printing burnish ink.

Abstract
Description
[装置構成]
図1は、本発明の一実施形態に係る印刷システムの概略構成を示す機能ブロック図である。この印刷システムは、印刷データ生成装置20、ラスタイメージ変換装置10、及び印刷装置としてのインクジェットプリンタ30を備える。
次に、印刷処理に先立つ治具の作成処理について説明する。図3は、印刷環境データの設定・編集処理を示すフローチャートである。
なお、前述の「フェンス」及び「コーナー」は、治具15の枠17の印刷の所要時間の短縮及びインク使用量の削減にも効果がある。「フェンス」及び「コーナー」の各辺長の最適値は、被印刷物31の形状(大きさ及び厚さ)に依存する為、入力部14aは、各辺長を編集する機能を有する。
なお、一度作成した治具は、他の印刷ジョブにおいても繰り返し使用することができる。この場合、ラスタイメージ変換装置10上では、記憶されている複数の印刷環境データを検索し、使用する治具レイアウトを選択すれば良い。
図7は、ラスタイメージ変換処理部12におけるラスタイメージ変換処理(印刷ワークフロー)を示すフローチャートである。
まず、予め、図3に示した印刷環境データの初期値設定等の印刷ジョブの設定を行っておく(ステップS21)。次に、ホットフォルダ11から印刷データを読み込む(ステップS22)。ここで、新たに読み込まれた印刷データに対して、印刷ジョブの編集が必要と判断された場合には(ステップS23)、印刷ジョブを編集する(ステップS24)。
印刷ジョブの編集の例としては、後述する複数の印刷ジョブのネスティング処理、及び印刷環境データの編集処理等がある。次に、印刷データの印刷テンプレートへの割り付けを含むラスタライズ処理が実行される(ステップと25)。この処理により、印刷テンプレートの各印刷スロットにラスタイメージデータ(CMYKデータ)が割り付けられる。
次に、図7のステップS25で説明した印刷データの印刷テンプレートへの割り付け処理の詳細について説明する。
なお、この処理は、上述した治具15を使用する場合には、インクジェットプリンタ30の図示しないテーブル(プラテン)に、テーブルの基準位置と治具15の基準位置O1とを合致させた状態で設置し、各枠17内に被印刷物31をセットした状態で起動される。但し、この処理は、上述した治具15の使用が必ずしも前提ではなく、印刷媒体に印刷スロットの形状を通常印刷した治具を使用しても良い。また、インクジェットプリンタ30の図示しないテーブル(プラテン)に直接印刷スロット16の外枠イメージを印刷して、それぞれの印刷スロット16に合わせて被印刷物31をセットするような場合にも、この割付処理は適用可能である。要は、被印刷物31が正しい印刷位置に配置されれば良い。
異なる複数の印刷データを、それぞれ印刷テンプレートの別々の印刷スロットに割り付けて印刷する場合、通常は、印刷データ生成装置20内において、複数の印刷データが例えば別々のPDFファイルとして作成され、それぞれ別々のPDFファイルを別々の印刷スロットに割り付けるための割り付け操作が必要であった。これに対し、本実施形態では、これら別々のPDFファイルを1つのマルチページのPDFファイルの印刷データとして、ラスタイメージ変換装置10に入力することにより、ラスタイメージ変換処理部12が、各ページを各印刷スロットに自動的に割り付ける機能と、その印刷ワークフローを有している。
図12は、二つの印刷データ(Job1,Job2)をネスティング処理してマルチページ・シングルレイヤの印刷データを作成する例を示している。ここで、「ネスティング処理」とは、複数の印刷データ(印刷ジョブ)を一つにまとめて処理する機能と、複数の印刷データを一つにまとめる際に、無駄なスペースが無くなるように各印刷データの配置を調整する機能とを含む処理である。しかし、この実施形態では、レイアウト情報が設定されていると、このレイアウト情報に従う割付処理が優先される。このため、ここで述べる「ネスティング処理」では、印刷データの統合によるマルチページ化のみを実行し、印刷データの配置は、レイアウト情報に従う。このようなネスティング処理は、印刷データ生成装置20で行っても良いし、ラスタイメージ変換装置10内の印刷ジョブの編集操作で行っても良い。
例えば、透明なスマホケースにUV硬化インクによる厚盛印刷を行うような場合、下地層としてホワイトインクを全面印刷し、その上にCMYKインクによる画像を印刷し、更にその上にバーニッシュインクを使用した厚盛印刷を行うといった、多層印刷をすることがある。以下、インクジェットプリンタ30のテーブル(プラテン)に対して、印刷層の数だけインクジェットのヘッドを副走査方向に往復させるマルチパス印刷方式によるマルチレイヤ印刷について例を挙げて説明するが、各層のインクを吐出するノズルを副走査方向に僅かずつずらして、各層のインクを同時に吐出しながら、ずらし量分のピッチで各印刷層の印刷を一度のヘッドスキャン動作で行うシングルパス印刷方式にも適用可能であることは言うまでも無い。
図18は、一つの印刷データ(Job1)からマルチページ・マルチレイヤの印刷データを生成する例を示す図である。ラスタイメージ変換装置10内において、一つの印刷データから、画像処理技術などを用いて、下地用の画像、カラー画像及びバーニッシュ画像等のレイヤを自動、又は半自動で抽出し、これらをそれぞれ第1ページ、第2ページ及び第3ページに割り付けた一つの印刷データを生成する。レイヤを自動生成する場合には、画像の全面を抽出、色の存在する部分を抽出、色の存在しない部分を抽出、ページ全体をフラットな任意の濃度とする画像、同画像の白黒の反転画像を抽出する等の処理を行うこともできる。また、レイヤを自動生成する場合、ブリーディング(原画よりも拡大)と、チョーク(原画よりも縮小)を指定する機能を有していても良い。なお、レイアウト情報の指定は、例えば図13で示したものと同様のものを使用することができる。
