Spine Width Calculator

How to set up Spine Width Calculator

The ability to calculate Spine Width has been added into the Fold Catalogue setup.

The Spine Width is calculated by summing the height of all sections and rounding the value up to the nearest mm (1/16” or 0.0625 of an inch)

The calculated spine width is shown in a hover over the ‘Imposition Size’ in Printing Details.

Rather than change an existing fold catalogue, you might want to consider creating new catalogue entries to include the Spine calculations.

The calculation is enabled by entering the number of spines to calculate on the Fold Catalogue entries. This will usually be ‘1’ entered into one of the two Spines fields:

We would also recommend adding a descriptor to the modified fold catalogue entry to denote a Spine Calculation is included:

The Spine Width details can be added to the Quote Description Template to show only when the Spine Width Calculator is used.

Use the format below to only show the Spine Width when it has a value:

This will generate a product description, incorporating the Spine Width (if it has been included in the selected fold catalogue):

Similar book product without the Spine Calculating fold catalogue used – the size does not show spine width details:

In custom quoting when a fold catalogue is used that has a Horizontal or Vertical Spine set to 1, the sum of the height of all sections is calculated into the flat size and returned in a hover in the printing details.

This hover shows on all section details; however, the calculated spine width is only added to the imposition size on the section that the Spine Enabled fold was applied to (Cover section in most cases).

Quoting with Spines

On a quote for a 320pp A4 Plus Cover Book, without a Spine calculating fold used, there is no Spine detail presented in a hover, the Imposition Size (which includes 3mm bleed) does not reflect the additional material required for the spine and the sheet size and total sheets may not suit if a spine was calculated for:

If the Fold Catalogue on the Cover section is changed to one with the Spine calculator enabled (note: the fold catalogue may be pre-selected and hidden on the template):

And the product price recalculated, a spine width has now been included into the imposition size calculations.

In this example the size of the spine forced IQ onto a larger stock size, printing the cover 2 up on a different press:

When the quote is accepted, the Spine Width value is brought thru onto the Production Job Bag.

It is displayed here in its unrounded format just below the product description:
