Printing position alignment method and printing apparatus

Multiple alignment patterns, each composed of first and second alignment pattern elements printed by forward and backward movements of a print head, respectively, are formed while the relative printing positions of the two elements are shifted. From optical characteristics data thereof, whether the data is influenced by a disturbance is determined. When the data is determined to be less influenced by the disturbance and therefore to be reliable, an adjusting value for aligning positions in printing in reciprocal movements is calculated by use of: data with the smallest relative printing position misalignment between the first and second alignment pattern elements; and data of optical characteristics close to the data. When the data is largely influence by the disturbance, a range of shifting of relative position is widened than that of the data less influenced by the disturbance so that more data pieces are used to obtain the adjusting value.

There is provided an inkjet printing apparatus which can restrict each of coloring of reflected light and image clarity within an allowable range required in each of a color mode and a monochromatic mode in any of the modes to output an image with a high grade. For this end, a print duty of each of the first image improving liquid and the second image improving liquid is set in such a manner that a ratio of the print duty of the first image improving liquid having low penetratability to the print duty of the second image improving liquid having high penetratability is higher in the monochromatic mode than that in the color mode. Thereby, an appropriate ratio and an appropriate amount of appropriate kinds of the image improving liquids are applied to each of the color mode and the monochromatic mode.

For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c 1 and a magenta nozzle array m 1 , that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

Techniques For Arrayed Printing of a Permanent Layer with Improved Speed and Accuracy

A repeatable manufacturing process uses a printer to deposits liquid for each product carried by a substrate to form respective thin films. The liquid is dried, cured or otherwise processed to form from the liquid a permanent layer of each respective product. To perform printing, each newly-introduced substrate is roughly mechanically aligned, with an optical system detecting sub-millimeter misalignment, and with software correcting for misalignment. Rendering of adjusted data is performed such that nozzles are variously assigned dependent on misalignment to deposit droplets in a regulated manner, to ensure precise deposition of liquid for each given area of the substrate. For example, applied to the manufacture of flat panel displays, software ensures that exactly the right amount of liquid is deposited for each “pixel” of the display, to minimize likelihood of visible discrepancies in the resultant display. 1.

In one example of the disclosure, an uncalibrated sensor may be calibrated. Calibrated sensor data is obtained. The data relates to an amount of light transmitted through an ink solution of a first colour as a function of ink concentration. An amount of light transmitted through an ink solution of the first colour is measured, using the uncalibrated sensor, at a plurality of ink concentrations. A calibration factor relating the light transmission of the calibrated sensor for the first colour and the light transmission of the uncalibrated sensor for the first colour is determined, using a processor, based on the obtained data and the measurements. 1. A method for calibrating an uncalibrated sensor , the method comprising:obtaining calibrated sensor data, the data relating to an amount of light transmitted through an ink solution of a first colour as a function of ink concentration;measuring, using the uncalibrated sensor, at a plurality of ink concentrations, an amount of light transmitted through an ink solution of the first colour; anddetermining, using a processor, based on the obtained data and the measurements, a calibration factor relating the light transmission of the calibrated sensor for the first colour and the light transmission of the uncalibrated sensor for the first colour.2. A method according to claim 1 , further comprising:storing the calibration factor in a storage medium associated with the uncalibrated sensor.3. A method according to claim 1 , further comprising:applying the calibration factor to data acquired using the uncalibrated sensor.4. A method according to claim 1 , further comprising:determining a relationship between a concentration of ink in an ink solution of the first colour and a concentration of ink in an ink solution of the second colour that result in the same amount of light being transmitted.5. A method according to claim 4 , further comprising:applying the determined relationship to data acquired using the uncalibrated sensor.6 ...

A production system acquires a plan of production of plural types of products to he produced through sequential attachment of prints, determines an order of production of the prints to be attached to the plural types of products, respectively, and produces the prints in the determined production order. 1. A production system comprising:a production plan acquisition unit that acquires a plan of production of plural types of products to be produced through sequential attachment of prints;a determining unit that determines order of production of the prints to be attached to the plural types of products, respectively, based on the production plan acquired by the production plan acquisition unit; anda production unit that produces the prints in the production order determined by the determining unit.2. The production system according to claim 1 , whereinthe determining unit determines the order of production of the prints so that order of production of the plural types of products to be produced through sequential attachment of the prints agrees with the order of production of the prints to be produced by the production unit according to each of the plural types.3. The production system according to claim 2 , whereinwhen the prints are consecutively attached to one type of products among the plural types and a plurality of products of the one type are consecutively produced, the determining unit determines the production order so that the prints corresponding to the one type are consecutively produced in a quantity corresponding to the quantity of production of the one type of products. This is a divisional application of U.S. patent application Ser. No. 16/054,795 filed Aug. 3, 2018, which is based on and claims priority under 35 US.C. § 119 from Japanese Patent Application No. 2018-055736 filed Mar. 23, 2018 and Japanese Patent Application No. 2018-073493 filed Apr. 5, 2018. The entire contents of all prior documents are incorporated by reference herein.The present ...
