Minimal G7

This control strip contains 21 patches for G7 conformance plus very basic TVI and overprints analysis.

Assessing an offset press used to require a dedicated press run which is very expensive, and is often not indicative of actual day-to-day production. For these reasons, we have developed multiple procedures to assess an offset press during live production. We have designed small control strips that can be placed in-between regular jobs. Reduced amount of patches and small size gives an opportunity to locate them in the gaps.

 

Minimal G7 in the gaps

 

Three-row compact version (Minimal G7 -3R)

 

 

When using a handheld instrument with a scan option like X-Rite eXact Scan or Techkon SpectroDens or using other instruments with a small aperture it is possible to reduce strip width to 3-4 mm  (1,5 / 2mm instrument aperture required).  If you are using a different instrument contact the vendor for detailed information.

 

Extended Minimal G7+Spot versions

Minimal G7 can be adopted to CMYK + SPOTs job very easily. Use Capture Inspector to add additional patches. In the following example four spot placeholders were added (two solids and two 50% tints/ Custom Spot 1 and Custom Spot 2).

Custom Spot is a placeholder - the user can assign any spot color from the library when working with CC Capture. It is a very flexible way that reduces time and effort.

Here you can find a step-by-step procedure on how to add placeholder patches to Minimal G7 
finally, the operator will be asked to assign placeholder patches with spot color references stored in Color Library/Pallete.

 

 

Such a control strip can work with any spots without the need to recreate each time. The operator may want to skip one or more placeholders using a DUD selection. 

 

Minimal G7 3R 

There are situations where we need a 3-row version. For example, i1iO with i1Pro 3 Plus requires large patches (16x16 mm or 16 x 20 mm). Also, some pocket instruments can measure control strips but the size has to be big enough.

Imagine a scenario when you need to evaluate the printing process (G7 or TVI) when printed on a high glossy substrate or substrate with some surface effects. A regular 0/45 spectrophotometer may not work properly and a spherical one has to be used instead. You may need to use for example Spectro 1 Pro Bridge that is D/0° SPIN and give an opportunity to measure Actual (Pure) Color without sheen effect. But this instrument has an 8 mm aperture and a minimal patch size is 10x10 mm but due to physical shape patch size needs to be larger as we don't know exactly where is aperture.
