The "stroke-width" items were eliminated in Ver4.5.0.
Solution:
4.2.4 In previous versions, there was a stroke-width setting to improve the readability of OCR marking, particularly when the character stroke is thick or thin. When the stroke width is set to Thick, the reader performs image-filtering to narrow the character stroke before reading. When the Stroke Width is set to Thin, the image-filtering is used to artificially thicken and then read the character stroke.
Version 4.5.0 has a function to automatically determine whether the image readability can be improved by making the character stroke thicker or thinner during filter tuning.
To optimize Config of OCR markings that use bold or thin characters in particular, you can accommodate the thickness of the characters by checking the [Filter] checkbox ([Setup] → [Tuning] tabbed page) prior to tuning.
