Description Douglas_Peale 2017-02-21 02:32:43 UTC
Description:
Using Avery 8167 return address labels with 20 rows of labels on a US letter page, the bottom label prints about 0.05" higher than the first. With a resolution of 1/100", this can not be fixed because a 0.01" change in the spacing results in a 0.2" shift of the last label. The labels are only 0.5" tall.
Please allow 0.001" resolution.

Steps to Reproduce:
1.try to change vertical pitch by 0.001"
2.
3.

Actual Results:  
vertical pitch does not change.
Try and change it by 0.005", and it changes by 0.01" instead.

Expected Results:
I expected to be able to adjust the alignment of the last label to match that of the 1st. Smallest step change moved the last label text way too far.


Reproducible: Always

User Profile Reset: No

Additional Info:
The spacing numbers in the template are correct, I am attempting to compensate for a slight scaling by the printer/printer driver.

This is issue on 5.2 as well, but may have not been fixed for 5.3, the Vertical Pitch only allows granularity of 1/100 of an inch.  

This results in an error in alignment on Avery form 5266 in addition to the form vertical pitch being incorrect at 0.68.  Avery form 5266 is 1/2" top and bottom margin and 10" of 15 labels at 0.666667 per label.  With vertical pitch set at 0.67 it results in a shift of 0.05" at the end of the sheet, or about 3.6 pts.  If using 0.66 it results in a negative shift of 0.10" at the end of the sheet, or about 7.2 pts.  The default for the label is being set to 0.68" vertical pitch, so this results in a 0.15" shift, or about 10.8 pts.  That's a 10 pt line shift by the end of the page, and unacceptable.  Even the 3.6 pts. error in rounding is unacceptable for label or form work.  

If the vertical pitch is revised to have a higher precision, then the resulting positions that are used for the frames being at 1/100" would only be off for 2 out of 3 labels, since 3 x 0.666667" would be 2.0000".  But better to increase precision on the frame's vertical position as well.  1/1000" would reduce the amount of rounding error, and accommodate for denominators of 8 (i.e. 0.125).

Sample document, please just do File/New/Labels and select Avery (US) and Label sheet 5266.

This seems to be an internationalization issue with the overall implementation of the software units of measurement for US and Imperial measurements.  

Inch denominations are typically 1/2, 1/4, 1/8, 1/16 increments for paper sizes, labels and forms.  1/8 of an inch (0.125) will require 3 decimal places of precision to accurately represent the units of measure. 1/16 of an inch (0.0625) will require 4 decimal places.

Although the metric system typically doesn't require more than 2 decimal places, it presents a usability issue for the US market.

Anywhere where Imperial/US units of measure are used this could present a reduction in functionality of the product.  This is more of an issue of precision on values that are derived and repetitive such as in the case of the label's vertical pitch.  

It would also be an issue for any spacing or margins that can not handle 1/8" or finer because of the 2 decimal place limitation.   This is essential for the proper creation of US forms or layout for printing on pre-printed forms.

This issue is a major usability flaw and still exists in the current 5.3 release.

No sample document required.  Use File/New/Labels, then select Avery Letter Size for Brand, and 5266 File Folder-Assorted for the Type on the Labels tab if you need a document.

If you need more explanation, let me know.
