n Mesh Opening w Wire Diameter d

The two most important variables of BOPPSD meshes are the mesh opening (w) and thewire diameter (d).

Example: BOPP SD 50/30

50 = Mesh opening w in microns30 = Wire diameter d in microns

n Mesh Fineness

The mesh neness identies the number ofwires per imperial inch (mesh count):

Mesh = 25.4 mm

(w/mm + d/mm)

n Open Area A 0

The open area describes the total open areain terms of mesh apertures across the entiresurface of the mesh. The bigger the openarea, the greater the colour throughput.

Open area A 0 = w 2

x 100% w + dExample: SD 50/30: 39%

( )

n Mesh Thickness DThe mesh thickness is determined by the wirediameter and the weaving technique. The

thickness measurement is taken with the meshuntensioned, using a gauge (measuring pressure1.8N) on a rigid base. The tolerance valuesfor unrolled mesh lie between +/- 2 to +/- 5microns, dependent upon mesh type. Insidethe roll, the tolerances are significantlyhigher.

n Theoretical ink deposit V th

The theoretical ink deposit describes thevolume of the open mesh calculated on the

area of the substrate. In the event of insufcientcolour lay down, a mesh with a high Vth should be used.

Vth cm3/m 2 = w 2

In comparison with synthetics, stainless steelmeshes exhibit the highest levels of exuralstrength and the least percentage of elongationin terms of elastic yield point.

When printing on non-absorbent substrates,off contact distance should be used. Theselected off contact distance must allow thescreen directly behind the squeegee to detachfrom the substrate. Only then will the screendetach cleanly and completely from the colour,a prerequisite for a sharp print with even colourlay down.

The required off contact distance is determinedby three factors:• Mesh tension• Rheology (ink viscosity)• Squeegee speed

n Fact

The higher the mesh tension, the lower theink viscosity and the slower the squeegeespeed, the smaller the off contact distancerequired.

When printing with off contact distance, the meshdeforms slightly, which has a negative effect onregistration accuracy. The smaller the off contactdistance, the less the mesh deforms and thereforethe better the registration accuracy.

Note: Doubling the off contact distance will

quadruple the image distortion.

n Fact 1. Stainless steel meshes can be tensioned

to higher values due to their greater exural strength.

2. Higher screen tensioning values facilitateuse of a smaller off contact distance.

3. The smaller the off contact distance,the better the registration accuracy.

Recommended screen tension values for BOPPSD stainless steel meshes are dependent uponthe print quality challenges.

Note: Selected BOPP SD meshes such as SDPLUS can be tensioned to values well beyond35 N/cm. When tensioning to these levels, the

stability of the frame should always be veried.Generally at this specication tension values of30-35 N/cm should be adequate to achieve aperfect end result.



Recommendations

Our recommendations are based on many years of cooperation with customers, suppliersand partners from across the screen printing industry.

n Frame SizesA frame which is too small in relation to theprint image will lead to overloading of themesh and to premature fatigue. In order tobenet from the full advantages of SDstainless steel meshes, attention should bepaid to the geometric relationships detailedin this drawing.

*K oder L, die kürzere Rahmenseite

n Frame SelectionBOPP SD stainless steel meshes are generallytensioned to higher values than syntheticmeshes, and the continuous developmentand rening of mesh production perpetuatesthis trend. The frame must be capable of takingup and retaining these levels of tension. Inorder to achieve high value, reproducibleprinted results, the frame must exhibit highdimensional stability.

n Fact Metal frames must be used with BOPPSD stainless steel meshes.

We recommend cast aluminium or hollowaluminium prole options, where meshes aretensioned onto the frames.

n TensioningNot all tensioning equipment available onthe market today is capable of achieving theabove average tension values required bySD stainless steel meshes. The image on Page 7shows a tensioning machine developedspecically for stainless steel meshes.

Correctly tensioned screens can achieveexceptionally long service lives. The followingguidelines have proved their value in practice:1. Bring meshes up to the recommended

tension value in stages. Raise tension inwarp and weft directions alternately,always beginning with the warpdirection.

2. During the tensioning process, checkthe tension values using a reliablemeasuring device such as a tensiometeror TEKTOMAT.

3. Leave the screen to rest for 15 – 30 min.

then check and tension again accord ingly.

n Aligning the Mesh

From a mechanical point of view, mountingframes at a 45% angle is the most stableoption. However, for technical reasons orwhen printing very large formats this angle isnot always optimal. Our recommendations:

1. Where possible, mount meshes at anangle (22 to 45°).

2. If mounting the frames at angle is notpossible, align the weft direction ofthe mesh to the squeegee.

n RegistrationIf registration accuracy does not meetrequirements despite minimum off contactdistance, then increasing the size of theframe whilst retaining the same image sizewill signicantly improve the end result.

Less print errors Less print errorsEven

Grünig-Interscreen AG

n Preparing the screenAs a result of meticulous degreasing, thesurface of the stainless steel wires providesan exceptional adhesive surface for all typesof lm and emulsion; no keying is necessary.

SD stainless steel meshes exhibit minimallevels of underexposure and can thereforebe exposed to light without problems.

n Printing(off contact distance and squeegee pressure)Selecting the correct off contact distance isdependent upon a range of factors such asmesh tension, ink viscosity and squeegeespeed, but also upon the print image itself .It is therefore impossible to give generalrecommendations for off contact distanceand squeegee pressure. In principle, thefollowing are valid:

1. Always begin with the smal lestpossible off contact distance.

2. If the ink/paste does not comeaway cleanly from the screen, thenincrease the off contact distance insmall steps.

3. Always work with the minimumsqueegee pressure.

Servicesn Specialist Cleaning Processes

Although our ne meshes achieve aboveaverage levels of cleanliness due to ourlow abrasion production processes, somemore challenging applications require specialdeep cleaning. Our purpose-designed mesh

cleaning installation operates using environ-mentally sound self contained systems, completewith an inspection and defect identication unitdesigned to pinpoint and electronically log theposition of any defects. The cleaning installationis located in our cleanroom area.

n CuttingCutting ne meshes manually was alwaysa demanding process in terms of accuracyof measurement, the quality of the cutedge and the overall integrity of the cutpiece. Today, this work is carried out byour computer controlled automatic cuttingmachine. On a work surface measuring

1800 x 1200mm, we can cut automaticallyto almost any pattern without touching byhuman hand. One signicant advantageof this is that cut pieces are packed withouthandling. The equipment is designed to cutwires up to 0.1mm in diameter and meshthicknesses up to 0.2mm.

n CalenderingRolling or calendaring improves ne mesheseven further. Our calendering plant wasdesigned and built to our own speci-cations. Maximum calendering force is 280tonnes, and the equipment can handlemesh widths up to 1600mm. We can manage

any selected calendering value, from softcalendering (10% reduction in thickness) toheavy calendering (30% reduction in thick-ness up to 45% for certain specications),achieving tolerances of+/- 2 micron acrossthe width and length of the roll.

n Bespoke MeshesOur extensive portfolio of screen printingmeshes enables us to respond to more than95% of standard market requirements. We

are also pleased to produce mesh to individualspecications on request, where quantitiesordered facilitate cost effective productionlevels.

Without highly developed technology and electronics, life in today’s information-based societywould not be possible. In our daily lives as well as in industry and commerce, machines takeon many tasks which we would be unable to manage without technical support. In thesefast-moving times, we have become accustomed to using high tech products, without beingaware that real technical achievements are hidden in these practical devices.

A signicant proportion of these products have been made possible by highly developedscreen printing processes. In the majority of cases, stainless steel meshes of the highestquality are used for these processes. BOPP SD meshes have been developed specically tomeet these challenges, and continuously optimised over the years.

Main Field of Application: Printing on Glass and CeramicsModern glass and ceramics printing places signicant demands on the printing process.Many of these products are classied as luxury goods, with correspondingly high qualitystandards in terms of decoration, outline and coloration, combined with low acceptedtolerance values. Very specic requirements have become the norm in this sector, such aspastes loaded with gold or individual shapes which present technically difcult print challenges.In addition, the image must also exhibit mechanical, thermal and chemical resistance.

Developed with practical relevance in mind, the BOPP GP range offers a selection of stainlesssteel meshes designed specically to meet the needs of today’s glass and ceramics printingindustries. BOPP GP meshes are particularly suitable for printing processes using thermo-plastic colours.

Solution

• Tension to recommended value• Check tension meter• Select stronger frames• Check adhesive• Check drying temperature• Extend tensioning time• Increase in 0.2mm steps• Check resistance• Adjust distance and speed

• Position more accurately

• Reduce off contact distance• Select larger frame• Check tension value of screen• Check squeegee pressure

• Select a mesh with a correspondinglyhigher/lower Vth

• Coat more thinly/thickly• Correct hardness of squeegee (shore value)• Check squeegee speed

• Align, check squeegee angle

• Check, thin ink• Check, change screen

• Wash off, change screen• Select a coarser mesh

• Increase carefully, monitor registration• Check distance and speed

• Select a mesh with a larger open area• Select ner mesh with higher mesh count• Select smaller off contact distance• Check coating or lm,

develop further• Check conductor design

• Check roughness, mill angles

Problem

1. Screen sticking,dragging:

2. Inaccurate registration,registration not correct

3. Incorrect ink/paste deposit thickness

4. Image not fully displayed

5. Image reproduction,marginal sharpness

The above-mentioned problems and their causes should not be considered in isolation; in most cases each will have an effect on another. It istherefore vital when testing to optimise processes that parameters are changed and the effects of the change established one by one.
