Quality levels for forms

On this page

1. Introduction

Quality Levels for Forms was developed by Public Works and Government Services Canada (PWGSC) in order to establish a common base of principles, practices and understanding between Federal Government departments and suppliers in selecting the print quality level most appropriate for the required forms.

Most forms are regarded as being at the Office Quality Level, although they can also be called up for the Prestige, Library or Informational Quality levels as defined in the document Quality Levels for Printing. Separate numerical tolerances are listed for each of the following types of forms:

  • Flat Forms
  • Snap-Sets
  • Continuous Forms (single-part and multi-part)

The specifications on each contract will state which of these three types is applicable in that specific contract. For each type of form the quality required in the delivered forms is expressed in measurable values as listed in this document.

This document is not designed to be applicable to forms, which involve:

  • Magnetic Ink Character Recognition (MICR)
  • Optical Character Recognition (OCR)
  • Mark Sensing

It is inherent in the quality level process that the quality of components supplied permits the production of the desired quality of the finished work.

No attempt has been made to restrict or control manufacturing process but rather this document sets the quality which must be achieved in the product. It is the responsibility of the supplier to ensure that the forms meet the quality requirements regardless of the method of manufacture. The contractor must supply forms, which conform to good workmanship, sound trade practices, satisfactory materials and consistency throughout the job. These requirements apply to all quality attributes whether or not they are specifically mentioned in this document.

Questions concerning a specific contract should be directed to the contracting officer named on the contract.

The consistency of positioning the image shall be such that when any two forms of identical image in a batch are placed one on top of the other with the left and top edges in alignment and when a pin-point is stuck through the image of the top form, the pinhole's position on the second form will coincide with its position relative to the image on the top form with a tolerance of ± 0.8 mm (1/32 in.).

2.1.3 Perforation positioning

Position accuracy of any vertical or horizontal perforation other than the outside edges shall be determined by measuring the distance from the perforation, at any given point, to the specified line of reference. The perforation shall be positioned as specified with a tolerance of ± 1.6 mm (1/16 in.).

2.1.4 Perforation tear

The force required to pull apart flat forms made up of paper with a basis weight between 55 and 90 g/m2 shall not be less than 1.75 nor more than 5 lb. per linear inch.

2.1.5 File hole positioning

The position of punched holes shall be measured from the specified edges of the form to the centre of the hole and from centre to centre of the holes. The holes shall be positioned as specified with a tolerance of:

2.2.3 Register, color to color

Misregister is recorded as the linear displacement of any color relative to another color on the same sheet. The maximum allowable misregister is ± 0.4 mm (1/64 in.).

2.2.4 Extraneous markings (scumming or set-off)

Lines, spots, smears or other extraneous (background) markings are assessed visually. Generalized scumming or tinting is assessed in terms of average reflection density of the affected area. Using a reflection densitometer zeroed on the unmarked paper, measure the background density with the visual filter setting. The maximum acceptable background density is 0.06.

2.2.5 Rub-resistance of printed image

Density measurements with a reflection densitometer are then made on the rub-off smear, having pre-zeroed the densitometer on an unmarked sample of the paper stock. An average density is calculated for the rub-off smear. The maximum acceptable density of the rub-off smear is 0.06.

This normally occurs with characters having an enclosed area such as the letters a, e and o. The degree of plugging is measured using a magnifier with a measuring reticle and is expressed as the percentage of the enclosed area that has been filled in. The maximum percent plugging allowed is 20%.

NOTE: Any six-point or smaller type is excluded from this requirement.

A test tube measuring about 15 mm in diameter and about 15 cm in length, containing sufficient lead shot to provide a total weight of 25 g, shall be allowed to rest vertically, by means of a suitable support, on the top of the snap-set. The support of the test tube should permit free vertical movement of the tube. The snap-set shall be quickly pulled out from beneath the test tube.
