- Fitment of more powerful dedusting units
- Pressure between blanket cylinders adjusted
- Lesser tacky inks used
- Newer varieties of less tacky blankets tried
- The
machineries and equipments in the paper mills frequently got cleaned in
the presence of the technical experts committees formed at various
intervals.
- A set of paper was freshly manufactured in the presence of committee and tried on the machine.
Inspite of conducting tests and trials as suggested, no meaningful result in eliminating the menace was achieved and the end result in every test and trial was almost zero in curbing the problem. Years rolled, none of the observations
of the committee members produced concrete results many of which played
less or no role at all on the vexed issue since the root cause lay
elsewhere, known only to few authorities in the paper mills that
supplied defective paper and the actual fact was kept hidden for mysterious reasons. What intrigued some of the think tankers was that while on the same conditions, the paper supplies of other mills left void, fluff free prints and when the paper supplies from the two mills which were fluff prone were used, the problem resurfaced again. As a test case, when some quantity of paper was produced in one of those two mills under the watchful eyes and presence of some members, the behaviour of those paper were found excellent on the printing machines. How could then the same machineries and equipments which were blamed to be covered with layers of dust and dirt able to produce in the presence of the members good lots of paper when the basic raw material used was the same ? This was unanswered question in the minds of isolated think tanks some of whose expression of doubts in different angles were brushed aside as irrelevant under certain pretexts and hierarchy. The unfortunate aspect of the entire exercise was that the attention of the committee members were cleverly diverted from the aspect of basic pulp making process and they concentrated only from the pulp filtering stations onward on the paper making process. Therefore for many years the problem of the paper supplies causing voids on print continued to occur on lots of paper received from the two mills without serious attempt made to track the root cause of the problem.
Over the years it became routine affair to constitute few task forces and committees with experts drawn from paper mill, machinery manufacturers and the printing units to address the problem which as expected failed to address the problem as the root cause of the problem though known to key personnel can not be contained altogether and at the same time on surface some action plan had to be stage managed to appease the workers and to show that corrective measures are taken. To consume the huge stocks of supplies already received and kept in the warehouse of the print houses and cleared on inspection and stocked in the warehouse of paper mills, as an interim measure to artificially reduce the magnitude of the problem, lots of good quality paper received from other mills and defective paper lots received from the specific two mills were mixed and issued for printing in the print houses and the productivity kept continued. In order to maintain industrial peace, some sops were also given to the workforce at intervals to compensate the lesser pay the workers got due to higher level of rejection beyond permissible limits. The key personnel allowed the problem to die down by itself over the next few years as nobody could offer alternate solution in redressing the problem. After several years when the alternate suppliers entered into the fray, and policy changed, the problem of higher percentage of waste accruing out of the paper automatically died down considerably.
However the big question that stood unanswered in the minds of thinkers was 'what exactly caused the void on print that haunted the presses even though the papers used to be pre inspected to get nod for dispatch'? After deeply studying the problem from various angles and discussion with several experts from the same field over many years, it became known that the root cause of the problem could have been the use of higher percentage of recycled paper in the pulp beyond permissible limits. This fact could not be shared at that time in public, lest it would have created industrial unrest and wrath of key personnel. At the same time the key personnel always believed that time was the best healing factor and bad experience with bad qualities of paper as has been discussed above in their print houses will slowly fade away from the mind and hearts of the personnel in the same print houses as time passes.
It was realized that in one of the two paper mills, usually the mill itself recycled part of the trimmings from their own finished stocks and added them with good pulp at some proportion while manufacturing the paper in order to reduce the cost of manufacturing paper. This is usual practice adapted by many other paper mills too. The excess stock of trimmings which remained beyond the scope of their processing unit was sold out. In this instant case few private firms which brought the trimmings from the mills recycled them along with other paper trimmings and produced ready to use recycled pulp cakes (paper pulp) and sold them back to the same mill when the mill faced shortage of main raw material- cotton comber. The ready to use paper pulp cakes had to be procured by the paper mill to offset the shortage of main raw material due to stringent procurement policies which hit them hard and production had to be somehow kept going even if it meant partial loss on profit to the print houses due to higher percentage of rejection and to whom the supplies were sent. The said paper mill thus knowingly continued production of defect prone paper by mixing good pulp plus some percentage of recycled paper from their own mills plus certain percentage of ready made recycled paper pulp cakes brought from the private entrepreneurs.
The recycled paper cakes contained
lots of foreign particles and shorter fibers both of which did not get digested and mix well with
the pure pulp. While manufacture, the small extraneous particles which passed through even filtering process lay embedded over the surface of the paper. Those partially embedded foreign particles struck on the
surface of the paper have been the culprit in producing severe fluff/ debris problem leading to void images on the print. Nobody seriously bothered to analyze how when the same mill continued to supply good quality paper to meet the printing requirement of a specific high value document (lest the supply would have been given to some other mills), the same mill continued to maintain bad supplies for printing low value documents in the same print houses.
In the case of the second mill whose supply was terrible, it was speculated that the supply of defective paper manufactured with higher percentage of inferior quality raw material was borne out of bad business practice. Gelatin was used by this mill for coating instead of PVA coating since it was cheaper raw material. The Gelatin too has lot of extraneous particles that prevent proper bonding of fibers especially on recycled paper. It was observed that the paper mill supplied defective paper lots with Gelatin as coating material instead of PVA coating and paper manufactured with more percentage of recycled paper in their supply along with defect free lots and thus indulged in unfair trade practices possibly due to the following reasons:
- To offer paper at lower rates in the face of stiff tenders.
- To reduce cost of manufacturing paper supply them at lower rate
- To recover recurring extra expenditures incurred on invisible cost expend while getting contract.
- To offset the extra expenditure expend on subsequent inspections
- To offset loss on profit due to several extraneous considerations which can not be spelt openly.
However one of those two mills was blacklisted from supplies later for many reasons. The speculation and observations on both the mills which supplied bad quality paper as discussed above have no documentary proof and were heard to be so. But it was unofficially known to key personnel who were firm in their belief that the above would have only been the reasons since the supplies received from other mills who manufactured with similar processing techniques with PVA coating instead of Gelatin were able to supply very good quality paper to the same print houses.
However with passage of time, when passive authorities left, bad suppliers blacklisted and changed, the menace of bad paper supply, mainly due to mixing of recycled paper with good pulp for manufacturing the paper sharply fell down automatically. As years passed every one had also forgotten the turbulent periods of the episodes. However an important lesson learnt was that when too much recycled paper is added in the paper pulp during manufacture of quality product required for production of high value document as was needed, they will indeed cause productivity loss.
