What is Maximum allowable reduction used for in ArtiosCAD's Standard Sheet Layout?
The Maximum allowable reduction is an additional tolerance that could theoretically be applied to each design to reduce its overall blank size in order for another row or column to fit on the sheet.
Assume this basic carton which will use Standard Sheet Layout with an exaggerated reduction of 3/4" for demonstration purposes:
With a Maximum allowable reduction of 3/4", results are as shown in the screenshot below. Notice that for Sheet 1, a fourth column exists which extends of the sheet and that reduction values exist for the Sheet and the Oneup.
Sheet 1 has a usable area of 39.657". The sheet Reduction value of 2.968, means that if the sheet's working area were to be extend by 2.968" to 42 5/8", a fourth column could be added to the layout.
Alternatively, each Oneup has a blank size in X of 10 15/32". If the blank size in X was reduced by .742", the resulting size of the Oneup would be 9.73", which would then allow a fourth column to be added to the original sheet working area of 39.657". Gutters of 1/4" are still accounted for.
When viewing the Sheet Layout Results dialog above, clicking Make Layout,will bring the the user to the MFG with layout as depicted in the dialog.
Neither the oneups nor the original sheet size are modified. The results shown in the Sheet Layout Results dialog are meant to be a guide. The user can cancel and determine if the maximum allowable reduction makes sense or not and opt for a different layout.
