1. A print quality control method, comprising the steps of:
providing a visual referring target on the printing substrate for color balance adjustment;
setting a specific halftone of black \u201cK\u201d as the referring monochrome grey tone (MGT);
creating a neutral grey tone (NGT), by accurately overprinting a cyan \u201cC\u201d, a magenta \u201cM\u201d, and a yellow \u201cY\u201d color according to a pre-determined halftone value percentage;
placing tightly both MGT and NGT next to each other across the printing surface; and
comparing both printed tones result to control the grey tones color balance.
2. The print quality control method of claim 1, wherein,
said method further comprises the steps of:
comparing said specific halftone of black \u201cK\u201d referring monochrome grey tone, (MGT), and said \u201cCMY\u201d neutral grey tone (NGT) to the grey tones values;
providing referring targets MGT and NGT, comparing the grey tones color balance changes, and making a fine color correction to achieve the neutral grey balance condition; and
when the result of MGT and NGT on the printed proof is balanced and visually similar in shade, the MGT and NGT are act as the target referring function for the future mass production quality control usages.
3. The print quality control method of claim 1 or 2, wherein, based on the appropriate unique pre-determined grey patches, suitable in size, forming grey images for referring to control color changes, placing next to each other, inverted in position, placed across the full job’s width and accurately registered in serial pattern for providing color balance correction information.
4. The print quality control method of claim 3, wherein,
both grey tones are appropriate unique defined visual referring patches, placing in position next to each other; and
in design of \u201cV\u201d, \u201cU\u201d, \u201cR\u201d and \u201cUnique Pre-determined\u201d defined shapes accurately registered in serial pattern for providing color balance correction information.
5. The print quality control method of claim 3, wherein,
both grey tones MGT and NGT color value structures are combined to be work product content images; and
required both grey tones MGT and NGT shape monitor images are designed based on the substrate space availability to determine a suitable size and shape to meet the best visual referring result.
6. The print quality control method of claim 3, wherein,
both grey tones are in serial pattern placed next to each other in the required \u201cR\u201d shape and accurately registered in serial pattern;
in this rectangular pattern, the accurately registered neutral grey tone pre-determine the halftone value cyan \u201cC\u201d, magenta \u201cM\u201d and yellow \u201cY\u201d color; and
the referring monochrome grey tone is created by a specific halftone of black \u201cK\u201d that are placed next to the neutral grey tone \u201cCMY\u201d as a controller group for visual color balancing correction purpose.
7. The print quality control method of claim 6, wherein,
a CMYK single color, halftone and SLUR indicating features are designed in between every two groups of rectangular pattern.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A connecting device that is capable of rotatably connecting a first component and a second component of a vehicle seat, comprising:
first and second connecting elements that are axially oppositely coupled to each other so as to be rotatable relative to each other; and
a retainer member that is arranged and constructed to clamp the first and second connecting elements, thereby preventing the first and second connecting elements from being axially separated from each other,
wherein the first and second connecting elements are arranged and constructed to be switched between a condition in which the first and second connecting elements can rotate relative to each other and a condition in which the first and second connecting elements can be prevented from rotating relative to each other,
wherein the second connecting element has a plurality of radially projected portions and a plurality of radially depressed portions that are respectively formed in a circumferential end surface thereof,
wherein the retainer member has a first retainer portion that is capable of axially contacting an outer surface of a circumferential periphery of the first connecting element, a second retainer portion that is capable of axially contacting an inner surface of a circumferential periphery of the second connecting element, a plurality of fixing portions that are axially projected from the second retainer portion toward the circumferential end surface of the second connecting element, and a plurality of supplemental retainer portions that are radially projected from the second retainer portion and are capable of axially contacting the radially projected portions of the second connecting element,
wherein the retainer member is positioned such that the fixing portions can engage the radially depressed portions of the second connecting element,
wherein end peripheries of the fixing portions are radially crimped, thereby forming a third retainer portion that is capable of axially contacting an outer surface of the circumferential periphery of the second connecting element, and
wherein the supplemental retainer portions are arranged and constructed to be axially supported by a support die of a crimping machine when the end peripheries of the fixing portions are crimped while the second retainer portion is axially supported by the support die.
2. The connecting device as defined in claim 1, wherein the supplemental retainer portions are shaped so as to extend in the same plane as the second retainer portion.
3. The connecting device as defined in claim 1, wherein the fixing portions and the supplemental retainer portions are respectively alternately positioned at equal intervals.
