Laminates made under vacuum and with good control of resin viscosity should not suffer from edge tapering. If there is any tapering of such laminates, it should be taken care of by the normal trimming which removes about 25mm per side. One other factor is the interleaving medium used between laminates during pressing; if this is uneven due to surface re-grinding, then the laminate thickness will mirror accordingly. The requirement is to control/minimise resin flow and this does not depend on how many laminates are pressed per book; in fact a high stack can contribute to reduced resin flow by slowing down the heat rise (thereby minimising the flow).
