The relationship between image resolution and screen frequency determines the quality of detail in the printed image. To produce a halftone image of the highest quality, you generally use an image resolution that is from 1. 5 to at most 2 times the screen frequency.  2, record 1, English, - image%20resolution

La relation entre la résolution de l’image et la linéature détermine la qualité du détail de l’image imprimée. En général, pour produire une image à demi-teintes de qualité optimale, la résolution d’image doit être égale à 1,5 ou 2 fois la linéature.  2, record 1, French, - r%C3%A9solution%20d%27image

During writing, the pattern of photoelectrons generated at the photocathode by the input light is imaged onto the target as a halftone potential pattern generated by secondary electrons. Scanning of the target surface by the reading beam may be accomplished either during writing or as a later step. As in other vidicon tubes, capacitive discharge of the target to cathode potential in reading automatically erases the target and leaves it prepared for a new image.  1, record 4, English, - sec%20vidicon%20tube

A star target printed along with the job represents a small section of image edge, such as type or a halftone dot. Changes in the edge shape due to slur, doubling, or "squash" are greatly magnified and can be detected readily. Due to the target's symmetrical design, such changes can be differentiated and assigned to the correct cause.  2, record 6, English, - star%20target
